What is test harness and Closure?
Explain in details?
Test Harness enables the automation of tests.It refers to the system test drivers and other supporting tools that requires to execute tests.It provides stubs and drivers which are small programs that interact with the software under test.
Test harness executes tests,by using a test library and generates a report.It requires that your test scripts are designed to handle different test scenarios and test data.
Why use Test Harness?
- Automate the testing process.
- Execute test suites of test cases.
- Generate associated test reports.
- Support for debugging.
- To record the test results for each one of the tests.
- Helps the developers to measure code coverage at a code level.
- Increase the productivity of the system through automation.
- Enhance the quality of software components and application.
- To handle the complex condition that testers are finding difficult to simulate.
Test are two contexts where Test Harness is used
1.Automation testing:It contains the test scripts,parameters necessary to run these scripts and gather results to analyze it.
2.Integration testing:It is used to put together two units of code or modules that interact with each other to check whether or not the combined behavior is as expected or not.
Test Harness Tools
- Junit: Tool used while using Java.
- Nunit: Tool used of using .Net framework.
Test Closure is a document that gives a summary if all the test conducted during the software development life cycle,it also gives a detailed analysis of the bugs removed and errors found.In other worlds.Test Closure is a memo that is prepared prior to formally completing the testing process.This memo contains a report of test cases executed,type and number of defects found,the density of defects,etc.
Stages of Test Closure:
The process of test closure is implemented with the assistance of six important stages,which help the team check and validates various components of the software before it is released for the end users.These stages involve continuous engagement of the testers as well as the team leads/manager,where they take measure to ensure the quality and effectiveness of the software.Hence,the six important stages of test closure are:
- Check planned deliverables.
- Close Incident Reports.
- Handover to Maintenance.
- Finalize & Archive Testware/Environment.
- Document System Acceptance.
- Analysis Best Practices.
Why Is Test Closure Required?
Test Closure is a very important part of software development.This is because it perform the following functions:
>> Formally Announce Closure.
>> Collate All Results.
>> Provide Detail Analysis.
>> Present Test Metrics To Client.
>> Adjudge Risk.
Test Closure Report:
Published after meeting the exit criteria as well as the successful completion of the testing phase,test closure report is prepared by the test lead to define various details about the process of testing,such as test passes carried out,their results,outstanding defects,exit criteria,testing performed,defects addressed,defect trend analysis,etc.
Moreover,this report is further reviewed by other stakeholders of the project,which ensures its accuracy.This report,in short ,indicates the culmination of testing and is an important part of Software Development Life Cycle(SDLC).
It refers to the system test drivers and other supporting tools that requires to execute tests. Test harness executes tests, by using a test library and generates a report. It requires that your test scripts are designed to handle different test scenarios and test data.
Test harness used in automation testing and integration testing.
Tools used are JUNIT and NUNIT
