 What would you do during the Test cases development phase in STLC?

• In this phase, the QA team writes the test case with a stepwise approach. The Test Case is then signed off by a Business Analyst after reviewing or rework on test cases in case modifications are required.

• Once test cases are ready, the QA team prepares the Test Data based on preconditions.

• The entry criteria of this phase are that the activities in test planning should be finished and the test plan should be ready.

• The exit criteria of this phase are that the test cases should be signed off, the test data should be ready and the test scripts prepared if automation is in scope.

• Test cases should be mapped with the Requirement Traceability Matrix to follow up on coverage of requirements if anything is missed.

Activities in the Test Case Development Phase

Following are the three activities that are carried out in the Test Case Development phase −

Test Scenarios Identification

Scenarios ease the testing and evaluation of a complex system. The following strategies help in creating good scenarios −

• Enumerate possible users, their actions and objectives.

• Evaluate users with a hacker's mindset and list possible scenarios of system abuse.

• List the system events and how does the system handle such requests.

• List benefits and create end-to-end tasks to check them.

• Read about similar systems and their behaviour.

• Studying complaints about competitors' products and their predecessors.

Test Cases Writing

A test case is a document, which includes test data, preconditions, expected results and postconditions, developed for a particular test scenario in order to verify compliance against a specific requirement.

The test Case acts as the starting point for test execution. After a set of input values is applied; the application has a definitive outcome and leaves the system at some endpoint which is also known as the execution postcondition.

Test Data Preparation

Test Data is used to execute the tests on test ware. Test data needs to be precise and exhaustive to uncover the defects. To accomplish these three objectives, it is followed by a stepwise approach as given below −

• Identify test resources or requirements
• Identify conditions/functionality to be tested
• Set priority test conditions
• Select conditions for testing
• Determine the expected result of the processing of test cases
• Create Test cases
• Document test conditions
• Conduct test
• Verify and correct test cases based on modifications
