Assertions are validation steps used in automated tests to verify that a web application behaves as expected. They ensure that elements, texts, attributes, or conditions meet the required criteria during test execution.
Testim provides various assertion methods to validate expected behaviors in automated tests. You can add assertions in Testim using its UI-based test editor or by writing custom JavaScript code.
CSS Property Assertion
- Go to the step where you need to perform validations.
- Click on Testim Predefined Steps → Click Validations → Click Validate CSS Property.
- In the dialog box, enter the Property Name as background-color and the Expected Value as, for example, #abcd.
Text Assertion using Testim Predefined Actions
- Go to the step where you need to perform validations.
- Click on Testim Predefined Steps → Click Actions → Click Add Extract Value Step.
- Now, click on the Extract Value block and set a variable name.
- Next, go to Predefined Steps → Click Validations → Click Validate Element Text, then pass the previously set variable name in the Text Validation block.
