What are the scripting techniques available for test automation?1. Linear scripting
- Here a simple record and playback is being used by a test engineer so as to automate a test flow/ test case of a system.
- There can be some redundant functions etc which are not required.
2. Structured scripting
- It is used to control structures in the scripts.
- They enable the testers to control the flow of the test script/ test case.
- They are typically ‘if-else’, ‘switch’, ‘for’, ‘while’ conditions/ statements which help in implementing the decision making in a script, to help perform some tasks iteratively and it has the capacity to call other common functions that need some common functionality
3. Shared scripting
- Here the scripts represent an application behavior which is shared amongst other scripts.
- The application which is under the test common functionality is scripted as shared scripts and these scripts are then called by other scripts.
- The scripts become modular in terms of common functionality.
- Due to the functionality of these scripts they cross the AUT boundary and can be used in other software applications as well.
4. Data driven scripting
- The data is separated from the scripts and is stored into the external repository as disk in form of files.
- This script contains only the programmed code.
- It is needed when the data needs to be varied over the test run.
- If the data undergoes any change the script need not be modified.
- The expected data is stored in the data files that have test data.
5. Keyword driven testing
- It is the control to check and execute operations in maintained with external data files.
- The external data file will test data and the operations/sequence of the test is planned in and extra library which needs to interpret this data in addition to the conventional script.
- It is an extension of data driven testing.
