Test Script

A test script is a testing work product modeling a software program (often written in a procedural scripting language) that executes a test suite of test cases.

The goals of a test script :
1) Automate the execution of test cases.
2) Support regression testing

Objectives of a single test script :
1) Execute each test case in the test suite.
2) Report the results of the test suite.

A test script provides the following benefits:
1) Automates a single test suite, thereby supporting regression testing.
2) Failure to produce test scripts makes regression testing more expensive and less likely to occur.

Contents
1) Test script objectives
2) Test preparation (e.g., to place objects under test into the appropriate pre-test states)
3) Test stimuli (e.g., to send test messages or raise test exceptions)
4) Expected behavior (i.e., test oracle)
5) Test reporting script
6) Test finalization script

STAF

The Software Testing Automation Framework (STAF) is an open source, multi-platform, multi-language framework designed around the idea of reusable components, called services (such as process invocation, resource management, logging, and monitoring). STAF removes the tedium of building an automation infrastructure, thus enabling you to focus on building your automation solution. The STAF framework provides the foundation upon which to build higher level solutions, and provides a pluggable approach supported across a large variety of platforms and languages.

Test Automation Framework

A Test Automation Framework is a set of assumptions, concepts and tools that provide support for automated software testing. The main advantage of such a framework is the low cost for maintenance. If there is change to any test case then only the test case file needs to be updated and the Driver Script and Startup script will remain the same. There's no need to update the scripts in case of changes to the application.

What should a test harness include?

Test harnesses should include the following capabilities:

1) A standard way to specify setup (i.e., creating an artificial runtime environment) and cleanup.

2) A method for selecting individual tests to run, or all tests.

3) A means of analyzing output for expected (or unexpected) results.

4) A standardized form of failure reporting.

Test Harness

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:

1) Test execution engine

2) 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.

The typical objectives of a test harness are to:

1) Automate the testing process.

2) Execute test suites of test cases.

3) Generate associated test reports.

Benefits of test harness :

1) Increased productivity due to automation of the testing process.

2) Increased probability that regression testing will occur.

3) Increased quality of software components and application.
