How Does Software Quality Work?
Software quality measures how well systems meet user and industry-standard expectations as well as best practice requirements.
Software quality encompasses multiple dimensions.
These aspects include functionality, reliability, maintainability, usability efficiency, portability, and security - essential factors that ensure the software is effective across different environments and meets user demands.
Quality software development depends upon a series of activities and processes, including requirements analysis and design, coding/testing/maintenance activities performed by software developers/testers/quality assurance specialists who ensure high standards are upheld when producing the final product.
What Are The Three C's of Software Quality?
The Three C's of software quality stand for Compatibility, Completeness, and Correctness.
- Correctness- refers to the ability of software programs to fulfill their intended functions without errors or bugs, making correctness an essential aspect of quality; it ensures it meets user needs and expectations.
- Completion- Completeness in software applications refers to their capacity to fulfill all their intended functions and satisfy requirements set by users and stakeholders. Ensuring this happens is significant; completeness guarantees it meets these objectives effectively and does the intended work.
- Consistency- refers to a software application's behavior across platforms and environments, providing predictability to ensure its reliability in multiple user scenarios. It guarantees consistent usage throughout its lifespan by various stakeholders.
What is Software Quality Management (SQM)?
Software Quality Management is how companies ensure their end product meets customer satisfaction and functions as intended through quality assurance, planning, and control.
Poor Software Quality Management often results in lower adoption and may thus hinder company goals for success.
Poor SQM practices can damage a company's reputation, decrease employee morale and cause errors and complications during patch and update releases.
SQM standards can be measured using maturity level assessment services or software services that use the Testing Maturity Model to measure quality management.
What is Automated Testing (Testing by Automation)?
Automated testing is an approach to automating software functionality's validation and quality evaluation against its requirements before the production release.
Computerized tests allow an organization to run tests faster without human testers being necessary; automated tests work best when applied repeatedly over significant test cases.
Test tools automate software testing through script execution. Test tools designed for automated testing examine software, compare test results, and report their outcomes; scripts written once can be reused again and again in subsequent computerized tests.
Automated tests offer organizations numerous unit, API, and regression testing applications.
Automated software testing helps simplify manual work into scripts - an idea worth considering if unit testing takes up significant resources within your Quality Assurance (QA) team. Continuous testing, integration, and delivery practices rely on automated tests that can be run anytime.
What is Automated Testing?
This is the general sequence of steps that follows an automated testing process:
- Choose a testing tool- The sort of testing and if the agency supports the platform where the product was produced are important considerations.
- Define the scope of automation- This is how much software testing will be automated.
- Plan design and development- This includes developing test scripts and planning the automation strategy.
- Automated scripts are used to test software- The tool should collect data and generate detailed test reports.
- Maintenance- Automated test scripts are updated and modified as necessary with newer software builds.
Automated tests include:
- Acceptance tests.
- API tests.
- Tests of integration
- Regression tests
- Smoke tests.
- Tests of the system
- Unit tests are an excellent way to test your unit.
- User interface (UI) tests.
An organization uses a framework of testing tools, practices, and standards to implement test automation.
Frameworks that facilitate data-driven, keyword-driven, or linear scripted testing are typically utilized. Linear scripting frames work effectively for small applications because it enable the rapid creation of test scripts with limited planning; however, this framework doesn't support reusable test scripts or modular frameworks to reduce redundant testing - though creating these takes more time and requires software testers to write scripts separately rather than creating modular frameworks that reuse previous test cases.
Data-driven frameworks let software testers generate scripts for multiple data sets at once and thus offer better coverage than modular models.
Keyword-based frameworks feature table-based lists defining keywords associated with each method of execution for software testers without extensive programming skills. -- functional when writing test scripts from scratch using keywords, as they make test cases more manageable and create scripts quickly and efficiently.
Hybrid models combine various practices to maximize benefits.
Selenium Robotium and Cypress are open-source frameworks and tools used for test automation.
Selenium automates and runs test parameters across web browsers and programming languages like C#, Java, and Python. Robotium helps Android testers create automatic system, functionality, and user acceptance tests. At the same time, Cypress covers integration unit end-to-end tests through its browser-based tool, which provides access to distributed object models in the browser and debugger support for further testing purposes.
Why Automated Tests?
Software products are always delivered with defects, despite rigorous software development team tests being carried out before release.
However, defects may still sneak through, and Test Automation offers ways of increasing software testing efficiency.
An individual performing manual software testing typically sits before their computer.
It systematically moves through each application screen, testing various input/usage combinations with expected behavior comparisons and recording their observations. Manual tests may be repeated during development cycles for source code updates and operating system and hardware configuration scenarios.
Unfortunately for them, many will only ever experience that for themselves. So for anyone wanting a break between times - or a good bargain! - then a visit here is what is required!
Automation testing tools make the testing process more manageable by playing back recorded and predefined actions, comparing them against their expected behavior, and reporting back to a test engineer whether manual tests were successful.
Automated tests are easy to repeat and extendible to perform tasks beyond manual testing capabilities. Therefore, intelligent managers have discovered automated software tests essential to successful development processes.
Automated software testing has long been considered essential to large software development companies while being costly and challenging for smaller firms to implement.
Tools provide powerful yet affordable testing software solutions explicitly designed to address this gap - yet are equally suitable for use at larger firms with longstanding reputations.
Automating Testing Saves Time and Money
Software testing must occur frequently during each development cycle to maintain quality software development processes.
Testing should occur each time source code changes are made to software releases; each release can then be tested against all supported operating systems and hardware platforms. Manual tests require time-intensive and costly repetition, whereas automated ones are faster; reduced repetition means cost reduction.
Automated software tests have even shown dramatic time savings by cutting repetitive test sessions by half to several hours with automation technology, saving costs along the way!
A Vastly Large Amount Increases the Test Coverage
Software testing automation can boost software quality by expanding both its scope and depth of tests.
Unattended tests allow longer runs that would otherwise be skipped when performed manually; multiple computers with various configurations may even be utilized during these runs. Automated software testing can assess internal states such as memory, file, and program states to see if an app behaves as expected while offering coverage that is never possible with manual tests alone.
Test automation uses thousands of complex test cases during every run, providing coverage impossible with manual methods alone.
Tests Improve Accuracy
Manual testing can be tedious, and even the most diligent testers make errors when doing manual tests.
In contrast, automated tests record results consistently and accurately. By eliminating repetitive manual testing, the time saved by automating tests allows testers to focus on developing more automated software tests for more complex features or creating new computerized tests altogether.
Automated Testing Does What Manual Testing Cannot
Automated tests offer the only feasible means for performing controlled web app testing with multiple users simultaneously.
They allow significant software and QA departments to simulate hundreds or tens of thousands of virtual users accessing software, web apps, and networks simultaneously.
Automated Testing Helps Both Developers and Testers
Developers can utilize shared automated tests to quickly identify issues before sending code off for Quality Assurance (QA) review.
When source code is checked in, these computerized tests run automatically when possible and notify members if any fail - saving developers time and increasing their confidence levels as coders.
The Morale of the QA and Development Teams Improves
Automated software testing enables teams to focus on engaging projects by automating repetitive tasks.
Team members gain confidence while honing skills, transferring these gains back into their organizations.
Types of Automated Testing Systems:
Functional Testing
Functional testing assesses software against applicable requirements/specifications sets, with particular attention paid to functionality testing of applications (generally called black box testing).
Black box testing (or behavioral testing) involves testing an element's functionality without diving too deeply into its internal workings or design; thus, its designer and structure remain unknown to its tester.
Functional testing entails testing the primary functions, usability features, and accessibility needs of users. Available tests encompass unit testing, integration tests, smoke tests, and user acceptance testing.
Unit Testing
Unit testing refers to testing individual components or functions to ensure they work as expected.
Unit tests should typically be implemented during application development and often constitute the application's first automated test run. Developers typically carry out unit testing before undertaking integration testing.
Unit tests can be highly beneficial in helping identify bugs early, therefore keeping repair costs down.
Furthermore, unit tests enable developers to understand how each unit of an application functions and make code more reusable. Small teams might benefit less. These sensors might not detect all bugs.
Techniques for unit testing can often be divided into three categories.
- Black box testing involves input and output testing as well as UI testing.
- White box testing is a test that evaluates the functionality of an application.
- Gray box testing is a testing method that involves the execution of test cases and test suites as well as performing risk analyses.
Integration Testing
Integrating testing is testing an entire application, from its design to execution, to ascertain that its functional requirements have been fulfilled.
Integration testing involves investigating how different modules interact when combined. Integration testing should always follow unit testing to ensure seamless functionality between all software parts. Integration testing can be accomplished using various approaches, including the Big Bang (sometimes called the Top-Down Approach), Bottom-Up Approach, and Top-Down Approach.
Smoke Testing
Smoke testing (sometimes called Build Validation Testing or Confidence Testing) refers to a set of minimal tests designed to assess the stability and viability of deployed software versions.
Smoke testing is an approach used to ascertain whether the main elements of an application are functional. Smoke tests can help assess whether an app should be abandoned due to a lack of functionality or progress through various testing phases.
Smoke testing typically occurs once integrated software functions have been built and, should any tests fail, will be sent back to its developers for modifications.
Quality Assurance Engineers usually conduct such smoke tests.
Nonfunctional Testing
Testing an application involves verifying its performance, reliability, and usability while testing various other nonfunctional aspects.
Functional testing focuses on what a product can do; quality assurance testing examines how well it does this job. Nonfunctional testing typically follows functional testing because it makes sense to ensure the product fulfills its functions before assessing its performance.
Nonfunctional tests encompass load testing and scalability assessments, compatibility checks, security assessments, performance measurements, and reliability evaluations.
Performance Testing
Performance testing aims to identify performance hurdles and optimize software for optimal user results.
Performance testing is essential in ensuring a software's success on the market, helping identify issues such as slow operation under heavy loads that users might experience. Performance testing of critical medical software is also vital to ensure it operates reliably in challenging environments.
Regression Testing
Regression testing falls within maintenance testing. Regression testing involves rerunning functional and nonfunctional tests following changes to software code or program that altered its functionality to see whether its performance differs after any code/program modifications have taken effect.
If the version varies significantly, then there has been regression. Regression testing aims to verify that code modifications have not caused adverse side effects on existing applications.
Keyword-Driven Testing
Keyword-driven testing involves creating data files containing keywords related to an application.
Each keyword represents actions necessary for the completion of specific steps of testing. Keyword-driven approaches involve identifying and linking specific words/phrases with actions; those actions will then automatically occur whenever any keyword is utilized.
Functional testing is a straightforward, reusable method that's straightforward to maintain and easy to plan before an app even gets created. Furthermore, available testers can leverage it with most automation tools for maximum effectiveness.
Data-Driven Testing
Data-driven testing refers to expanding automated test cases by gathering external information stored in spreadsheets or tables and feeding it back into test cases.
Data-driven testing is often more cost-effective because testers must evaluate multiple data sets simultaneously rather than developing tests for every possible data source separately. Creating tests for every potential data set would take much more time and resources compared with using this approach instead.
Data-driven tests enable one test to cover multiple data sets simultaneously, providing consistent results while saving resources and time.
Reusability makes data-driven tests an attractive option that can be performed during any phase of software development without negatively affecting test data sets. Understanding the limitations and applicability of various automated testing types will enable you to plan test automation more effectively.
Note that no testing type can deliver optimal results in all circumstances; multiple forms of test automation must be combined to produce maximum ROI.
Benefits of Test Automation: 11 Reasons for Automating in 2023
Let's dive into the benefits of test automation in this article.
Faster Feedback Cycle - Feedback for newly developed features may require quite some time without test automation.
In contrast, automation could reduce that cycle and validate stages faster.
Test automation can be particularly advantageous, enabling early identification of bugs or issues and thus increasing team efficiency.
1. The Saves time
Your team can reduce time spent validating new features by automating their testing process, saving effort and resources when validating features for release.
Automation also facilitates communication across departments such as marketing, design, and product ownership that rely on these results; their logs for automated tests can easily be accessed to see what is happening.
2. Reduced Business Expenses
Your company can save money with automated testing environments. Manual testing should never be undertaken, as it has significant ramifications on projects.
Installing and configuring an automated testing environment takes both time and money.
In addition, a computerized test tool might need to be purchased to help establish a stable testing environment.
3. High Test Coverage
Manual testing limits the number of tests you can run; automated testing gives you more freedom and allows more tests to be written quickly for inclusion into a computerized suite - increasing its coverage while leading to applications with more excellent quality standards.
Automated testing gives developers more scope to create detailed tests to cover complex use cases. It is ideal for lengthy tests that might otherwise go undone during manual testing.
4. Reusability Test Suite
Building your automated test suite may seem intimidating initially, but once defined, and it becomes straightforward to reuse these tests for different use cases or in other projects - you could even connect another project directly to it!
As someone familiar with how to set up an automated testing suite and all its accompanying tools - like Continuous Integration (CI) pipeline - it should be easy for you to establish test automation in new projects.
You have all this knowledge at your fingertips that could be useful during their creation and deployment.
5. Faster Time to Market
As previously discussed, test automation allows for continuous testing and validation of newly designed features, speeding product launch by shortening feedback/test cycles and providing faster product support cycles.
6. Get Better Insights
Automated testing often provides more significant insights when specific tests fail than manual testing.
Automation not only shows insight into an application but can also display memory contents, data tables, files, and internal states, allowing developers to locate issues within it.
7. Increased Accuracy
Even experienced testing engineers make mistakes when performing manual testing; errors are more likely to appear when testing complex use cases.
Automated tests, on the other hand, provide 100% accuracy because their outcomes always produce identical results.
8. Automated Testing Provides More Features
Automated test suites offer additional benefits; for instance, they can simulate thousands of virtual users interacting with your web app to test its behavior - something manual testing cannot replicate effectively and can save developers significant amounts of time.
9. Reduced Stress On QA Team
Implementing an automated testing strategy gives your QA team more time and space to focus on other tasks than manual testing; engineers' job descriptions become more engaging when manual testing is no longer part of their daily duties.
Testing automation allows QA engineers to design new tools that will enhance and modernize an already established testing suite.
10. You Can Quickly Determine the Stability of Your Build
Automating tests can be invaluable in helping you assess the stability of a build.
Smoke testing is used to verify this stability; however, this approach often takes longer and requires manual intervention from testing engineers, such as creating databases of test results.
Automating smoke testing with test automation provides another convenient option.
Test automation enables smoke tests to run by automatically creating and populating appropriate databases - providing a quick assessment of building stability quickly and accurately. The automatic build verification system & releaser software system aim to verify and release automatically constructed products as soon as possible.
11. Eliminate Human Error
Manual testing leaves humans the potential for human errors; it makes sense to automate testing to reduce errors significantly to protect complex scenarios from these mistakes.
Although test automation cannot eliminate every mishap during manual testing, it significantly reduces it and its subsequent errors.
