The U.S. Bureau of Labor Statistics (BLS) classifies QA testers under "Software Quality Assurance Analysts and Testers," recognizing the role as a distinct occupation within the software development field.[3]
History
The practice of software testing emerged in the 1950s alongside early computer programming. During this period, programmers were generally responsible for testing their own code, an approach that frequently resulted in undetected errors.[4]
As software systems increased in complexity during the 1970s and 1980s, the limitations of developer self-testing became apparent. Glenford Myers argued in his 1979 book The Art of Software Testing that testing should be performed by individuals other than those who wrote the code, establishing a theoretical foundation for the dedicated tester role.[4]
By the 1980s and 1990s, many organizations had established separate quality assurance departments with dedicated testing staff.[5] The waterfall model of software development prevalent during this era treated testing as a distinct phase occurring after development was complete.[2]
The founding of the International Software Testing Qualifications Board (ISTQB) in 2002 represented a significant step in formalizing the profession through standardized certifications and a defined body of knowledge.[1]
The adoption of Agile methodologies beginning in the early 2000s altered the QA tester role. Rather than operating in a separate phase, testers became integrated into cross-functional development teams, participating throughout the development process.[6]
Role and responsibilities
Overview
QA testers evaluate software products by executing tests, documenting results, and reporting defects to development teams. The scope of the role varies depending on the organization, project, and software development methodology in use.[5]
According to the ISTQB Foundation Level Syllabus, core testing activities include test planning, test analysis, test design, test implementation, test execution, and test completion.[1]
Test planning and design
QA testers participate in the creation of test plans, which outline the scope, approach, resources, and schedule of testing activities. They develop test cases based on software requirements, specifications, and design documents.[7]
Defect management
When testers identify discrepancies between expected and actual software behavior, they document these as defects in bug tracking systems. Defect reports typically include steps to reproduce the issue, expected versus actual results, severity classification, and supporting evidence such as screenshots or log files.[5]
Documentation
QA testers produce several types of documentation during the testing process, including:
- Test plans, which outline testing strategy, scope, and resources[7]
- Test cases, which describe detailed steps for verifying specific functionality
- Defect reports, which document identified software bugs
- Test summary reports, which provide an overview of testing outcomes[1]
Types of testing
QA testers may perform or specialize in various types of testing, categorized by objective and approach:
| Type | Description | Reference |
|---|---|---|
| Functional testing | Verifies that software functions conform to requirements | [1] |
| Regression testing | Confirms that previously working functionality remains intact after code changes | [4] |
| Integration testing | Evaluates interactions between integrated software components or systems | [2] |
| User acceptance testing (UAT) | Validates that the system meets business requirements and is acceptable to end users | [1] |
| Performance testing | Assesses system behavior under various load conditions | [8] |
| Security testing | Identifies vulnerabilities, threats, and risks in software | [9] |
| Usability testing | Evaluates the ease with which users can interact with the software | [1] |
| Compatibility testing | Verifies that software operates correctly across different environments, browsers, or devices | [5] |
| Exploratory testing | Simultaneous test design and execution guided by the tester's knowledge and intuition | [10] |
Testing approaches
Manual testing
Manual testing is the process of executing test cases by hand, without the use of automation tools. The tester interacts with the software as an end user would, observing behavior and comparing it to expected results. Manual testing is often used for exploratory testing, usability testing, and ad-hoc testing scenarios where human judgment is required.[5]
Test automation
Test automation involves using specialized software tools to execute tests, compare outcomes to expected results, and report findings. Automation is commonly applied to regression testing, performance testing, and other repetitive testing activities.[11]
Widely used test automation frameworks and tools include:
| Tool | Primary use |
|---|---|
| Selenium | Web application testing |
| Appium | Mobile application testing |
| JUnit | Java unit testing |
| pytest | Python testing |
| Cypress | JavaScript end-to-end testing |
| JMeter | Performance testing |
Agile testing
In Agile environments, QA testers work as part of cross-functional teams and participate in iterative development cycles known as sprints. Testing activities occur continuously rather than in a dedicated phase.[6]
Agile testers typically participate in:
- Sprint planning sessions
- Daily stand-up meetings
- Continuous integration workflows
- Sprint retrospectives[6]
Skills and qualifications
Education
Educational requirements for QA testers vary by organization. According to the BLS, many positions require a bachelor's degree in computer science, software engineering, information technology, or a related field, though some employers accept equivalent work experience.[3]
Certifications
Several professional organizations offer certifications for software testers:
| Certification | Issuing body | Description |
|---|---|---|
| Certified Tester Foundation Level (CTFL) | ISTQB | Entry-level certification covering fundamental testing concepts[1] |
| Certified Tester Advanced Level | ISTQB | Advanced certification with specializations in test management, test analysis, and technical test analysis[1] |
| Certified Software Tester (CST) | Quality Assurance Institute (QAI) | Certification covering software testing principles and practices |
| ASTQB Certified Mobile Tester | ASTQB | Specialization in mobile application testing |
Technical competencies
QA testers commonly require knowledge of bug tracking systems such as Jira or Bugzilla, test management tools, SQL for database verification, and API testing tools.[10] Testers working in automation require programming skills in languages such as Java, Python, or JavaScript.[11]
Industry standards
Several international standards provide frameworks for software testing practices:
- ISO/IEC/IEEE 29119: A series of international standards for software testing that defines testing concepts, processes, documentation, techniques, and keyword-driven testing[12]
- IEEE 829: Standard for software and system test documentation[7]
- CMMI: Capability Maturity Model Integration, which includes process areas relevant to verification and validation[13]
Work environments and industries
QA testers are employed across a range of industries. The BLS notes that the largest employers of software quality assurance analysts include computer systems design firms, finance and insurance companies, and software publishers.[3]
Video game testing
Within the video game industry, QA testers (often called game testers) focus on identifying bugs, evaluating gameplay mechanics, and verifying compliance with platform requirements. Game testing has received media attention for issues related to working conditions, including extended work hours during crunch periods.[14]
Employment models
QA testers may be employed as full-time staff within development organizations, as contractors through staffing agencies, or through crowdsourced testing platforms that distribute testing tasks to geographically distributed testers.[15]
Career development
The BLS categorizes the role under its broader occupational classification for software developers, quality assurance analysts, and testers. The bureau projects employment in this combined category to grow 25 percent from 2022 to 2032, which is described as "much faster than the average for all occupations."[3]
Career advancement for QA testers may involve progression to senior testing roles, specialization in areas such as test automation or performance testing, transition to Software Development Engineer in Test (SDET) positions, or movement into test management.[6] Some testers transition into related roles such as business analyst, project manager, or software developer.[3]
Challenges
Software testing literature identifies several ongoing challenges in the QA tester role:
- Test coverage: Achieving comprehensive testing of complex systems within limited time and resources is a persistent challenge.[4]
- Rapidly evolving technology: QA testers must continuously update their skills to keep pace with new platforms, frameworks, and development practices.[10]
- Communication: Effective communication between testers and developers regarding defect reports and quality expectations is critical but can be difficult in practice.[5]
- Time constraints: Testing is frequently compressed when development schedules are delayed, placing pressure on QA teams to maintain thoroughness.[6]
Future trends
The QA testing profession continues to evolve with emerging trends. The application of artificial intelligence and machine learning to software testing has gained attention as a means of generating and optimizing test cases.[16] Shift-left testing, which involves integrating testing earlier in the development process, has become increasingly adopted alongside DevOps practices and continuous testing within CI/CD pipelines.[6]
