In software testing, a test harness or automated test
framework is a collection of software and test data
configured to test a program unit by running it under
varying conditions and monitoring its behavior and outputs.

It has two main parts: the Test execution engine and the
Test script repository.

Test harnesses allow for the automation of tests. They can
call functions with supplied parameters and print out and
compare the results to the desired value. The test harness
is a hook to the developed code, which can be tested using
an automation framework.

A test harness should allow specific tests to run (this
helps in optimizing), orchestrate a runtime environment, and
provide a capability to analyze results.

The typical objectives of a test harness are to:

* Automate the testing process.
* Execute test suites of test cases.
* Generate associated test reports.

A test harness may provide some of the following benefits:

* Increased productivity due to automation of the
testing process.
* Increased probability that regression testing will occur.
* Increased quality of software components and application.

A test harness provides a mechanism for controlling or
applying a test.

It is a huge benefit to separate the data from the test scripts. So, another part of the test harness would be the data repository. Here, we use several tables to identify elements and their properties and their relationships among different environments. By using this method, we can pull the element attributes for a given element based on the environment in which we are running our test. This allows the elements to have different properties in different environments, and we never have to use an if-then-else statement to determine which properties to use.

Remember that decoupling is good, so separate components of the framework into the smallest pieces you can manage. You then have the added benefit of being able to replace components with better ones if they become available. If a new engine comes out, simply change the engine. This may require a rewrite of your test logic, or test scripts, but you may be able to do this quickly using regular expressions, or a code conversion tool. If a better database comes out, change the db. If you code it right, all you have to do is change a connection string and your queries if needed. It may be a lot of work, but if the end result is faster and more efficient automation, it may be worth it.

Test harness is testing the contents of the server. It may
be of anything say, Java test, Mime type test, audio, video
test etc.. It is done before the server is lanched to
custmer use(Commercial). We can say test harness as a pre
testing of the server(Contents in the server)
It is mostly done in mobile handsets(wireless).
