Phases of Software Testing Life Cycle

The software testing life cycle phases consist of multiple stages designed to ensure comprehensive test coverage and defect-free software. Each phase has specific objectives, deliverables, and entry-exit criteria.

Let’s take a close look at these:

1. Requirement Analysis

The initial stage of STLC requires examining software requirements to determine what aspects should be tested. Testing teams receive input from stakeholders about both their functional requirements while also learning about non-functional specifications.

Key activities include:

• The evaluation of software requirement specifications (SRS) along with functional requirement documents (FRD) is performed.
• Identifying testable and non-testable requirements.
• The development of a Requirement Traceability Matrix (RTM) allows for linking test cases with requirements.
• Knowing the system architecture enables teams to establish testing boundaries.
• Testing operations need to recognize project factors and collaboration points that pose potential challenges to the testing process.
• The first steps entail establishing testing targets and ordering them according to business requirements.

2. Test Planning

The testing strategy development integrates three elements: complete testing methodology together with planning methods and necessary resource distribution. The entire testing process gets its base from this phase.

Activities in this phase comprise:

• The testing initiative requires both goal definition along boundary definitions.
• Testing projects need estimates of required duration and spending along with labor requirements for their execution.
• The selection of testing tools alongside the selection of frameworks and methodologies between manual and automated testing represents one of the tasks in this phase.
• The testing team requires the identification of specific roles and corresponding responsibilities.
• The team works to establish plans that reduce risks and create contingencies before moving forward.
• The testing phase will use established entry and exit criteria during each phase of testing.
• The project requires a detailed specification of testing facilities together with required infrastructure systems.

3. Test Case Development

The testing design stage creates test scenarios from previously identified requirements while creating necessary test data for evaluation purposes.

Key tasks include:

• The development of precise test cases and test scripts must include all necessary functional elements.
• The test designer develops both standard test scenarios and alternative test scenarios known as positive and negative test scenarios.
• The selection of test cases happens according to their importance levels for important system functionalities together with their identified risk factors.
• The plan for automation scripts becomes necessary when automation testing is used.
• A review of test cases by peers guarantees both their accuracy and their completeness level.
• The development of testable scripts that will be useful during future regression testing periods.
• The purpose of this process is to adequately link test cases with business requirements for clear documentation purposes.

4. Test Environment Setup

It is essential to develop a test environment that supports accurate test case execution.

This phase involves:

• The test environment requires a setup that includes hardware systems as well as software platforms together with networks and database structures
• The required test scenarios need testing data to be set up
• The technology ensures proper connection functionality between the application under test (AUT) and outside systems
• The environment needs to be validated through smoke testing until execution starts
• ·         Organizational efforts to solve environment-related problems will stop execution delays from occurring
• ·         Testing of performance and load needs real conditions simulation

5. Test Execution

Test execution starts the actual testing phase which uses the test cases already developed.

The process includes:

• The execution of manual along automated test cases takes place.
• A defect management system serves for defect documentation.
• The process requires the classification of defects according to their priority level and severity rating.
• Developers receive assistance from testers during issue-resolution activities.
• The system stability is checked after defect resolution through regression testing.
• Maintaining test logs, screenshots, and evidence of test execution.
• The collected test results enable both analysis and reporting purposes.

6. Test Closure

The final phase of STLC involves evaluating the overall testing process and ensuring all objectives have been met.

Activities consist of:

• Preparing test summary reports detailing test coverage, defects, and test effectiveness.
• Conducting retrospective meetings to discuss challenges and lessons learned.
• Archiving test artifacts, including cases, scripts, and defect reports for future reference.
• Ensuring all outstanding issues are addressed before signing off on testing.
• Gaining final approval from stakeholders and concluding the testing phase.
• Suggesting improvements for future testing cycles.

It is a must for students to achieve excellent scores in practical sessions for each SLTC phase and prove their worth before they are ready to sit for interviews. To do that, students may be required to do further studies and read beyond their syllabus. But sadly, due to the existing study pressure, it often becomes unimaginable to walk the extra road to achieve such excellence.

Writing critical assignments, preparing for exams, and most importantly, attending regular classes can be very demanding and draining. After completing their regular academic work, most of the time students are left with no energy to make extra efforts. But what if one can get someone to take care of his/her online classes and give space to do extra reading? Yes, it’s possible. If you are stuck in a similar situation, without thinking much, connect with an online exam help service and ask can you take my online exam for me?

Upon receiving such a request from a customer, they jump in to provide the solution to this problem. By taking a pocket-friendly amount, they assign an exam expert to appear in the online exam and help students get the grades they always wanted. Experts are highly experienced in using popular LMS like Edmodo, Canvas, Blackboard, etc., and can sign in and attend the test without any issues.
