What is TEST HARNESS? Tools & Examples

In the context of Software Testing, the Test Harness
In the realm of software testing, the term “Test Harness” refers to a collection of stubs, drivers, and various other supporting tools that are necessary for automating test execution. The test harness generates test reports in addition to carrying out tests with the assistance of a test library. The test harness is where all of the necessary information, such as test cases, the target deployment port (TDP), the source file being tested, stubs, and so on, is stored.

Test Harness

Why use Test Harness?

Introducing automation into the testing process Running test suites comprised of individual test cases
Produce accompanying reports for the tests.
Support for debugging
In order to keep track of the test results for each individual test,
Helps developers measure the amount of code that has been executed at a given level
Automating more of the system’s processes will boost its overall efficiency.

There are two contexts where Test Harness is used

Improve both the individual software components and the application overall.
In order to manage the complicated condition that testers are having trouble simulating.
There are two different situations in which the Test Harness is utilised.
Testing with automation: It includes the test scripts, as well as the settings that are required in order to run these scripts and collect results for analysis.
The testing of integration: It is used to put together two different units of code or modules that interact with one other in order to check whether or not the combined behaviour is as expected or not.

Test Harness Tools

Junit is a tool that is used when working with Java, while Nunit is a tool that is used when working with.

Test Harness Vs Test Framework

Test Harness Test Automation Framework
  • A test harness is composed of drivers and stubs, which are small dummy programs that interact with the software under test
  • It is a set of processes, procedures, abstract concept and an environment in which automated tests are designed and implemented
  • You can not “Record & Playback” script in Test Harness
  • A tester can manually “Record & Playback” script in this framework
  • Test harness contains all the information needed to compile and run a test like test cases, target deployment port(TDP), source file under test, stubs, etc.
  • Test automation framework contains information like test library, testing tools, automated testing practices, a testing platform, etc.
  • A test harness is categorized into
    • Automation Testing
    • Integration Testing
