Step 3: Create a test case

If you are not familiar on how to create a simple test case, refer to create a testcase

Step 4: Create a test steps to enter the email address where the OTP is to be sent

We will enter the email address provided by Testsigma using the Mailbox test data type in the test step.

In your test case, add a test step to enter the email in the email field on your application page.
Clear the test data placeholder and select the &|Mailbox| test data type from the suggestions list. An overlay showing the list of available Email addresses will open up.
Next, use the NLP Click on SendOTPto generate the OTP.

Step 5: Create a test step to fetch the OTP from the mailbox

We will use the test data generators available in Testsigma to fetch the OTP from the Mailbox selected in the previous step.

Add a test step to enter the OTP Code in the OTP Field. For this, select the NLP Enter test data in the EmailOTP field
Clear the test data placeholder and select the !|Function| test data type
Search and select the Test Data generator function !|MailboxFunctions - getOTP|
Enter the below arguments for the function and create the test step.
1. Regex: The Regex command specifies the format of the OTP i.e alphanumeric or pure number or pure alphabetical etc. For example: for an OTP which is a number with a length of 4 to 8, we can use the regular expression \d{4,8}.
2. Mailbox: The Mailbox is the pre-configured email ID to which the OTP is sent. In this case it is automation@testsigatech.com
3. Timeout: How long should be the wait time for the OTP to be generated
Once these values are passed the MailBox reader will use the parameters to read the generated OTP.
