Adding For Loops in Test Cases

For Loops are a powerful tool that will let us repeat operations. A For Loop loops a block of steps through each dataset (which is a multi-column, multi-row variable) in a test data profile. The loop ends when it reaches the end of the dataset or when a break is encountered.

Thus using For Loops, you can run the same test with a subset of test data. For instance, say you have a test data profile in the format below:

If you want to run a test case based on the above test data profile, but you just want to run it for rows 1 to 3, then you use a for loop.

Prerequisites

• Create a test case
• Create a test data profile

Using For Loop in Test Cases

1. Navigate to Create Tests > Test Cases, and click on Create Test Case.
2. On Test Case Details page, click on the option on the left side of the test step.
3. This will open a side panel.
4. Hover over to the options and click on For Loop.

5. This option opens a drop down of NLPs that can be used inside the test step.

   • If you want to iterate through all the data sets of your test data profile from start to end use the below NLP:
   • If you want to start the index at a specific number and end the index at a specific number use the below NLP:
     

   Sometimes you only want to work with a subset of the data sets of your test data profile. The subset of the data sets can be filtered based on data set name and parameter.

   • To filter test data profile based on data set name use the following NLP:

   The data set names can be subjected to advanced filtering based on the keywords contains,startswith,endswith,IN and the different data types supported by Testsigma. For more information refer to data types .

   • To filter test data profile based on parameter value use the below NLP:
   • Another NLP to filter test data profile based on parameter value is the following:
6. Select the suitable NLP to include in the test step and finish creating For Loop test step.

Additional actions possible on iteration count

1. Store: Iteration count is the current count that is being iterated in a for loop in Testsigma. This Iteration Count can be stored into a variable for later use. Below is how the syntax for the Store NLP looks like:

2. if: The test data set values, from a test data profile being iterated, can be compared within an if condition too. Below screenshot shows the NLP (The NLP can be added as a part of add-on “String Compare”. You can find the add-ons to use here: https://testsigma.com/addons):
