All the “tests” content are not executing when sending a request from the “flow” tab, how can I fix it?
Hey @security-saganist-14 !
Couple of things to check that may be the cause here:
- Script Visibility: Firstly, make sure that the test scripts are visible in the “Tests” tab for each request where you expect them to run.
- Errors in the Scripts: If there are syntax errors or other issues in your test scripts, they might fail to execute. Check the Postman Console for any error messages related to your test scripts.
- Environment Variables: If your tests rely on environment variables, ensure the correct environment is selected. Sometimes, tests might not execute as expected if the required environment variables are missing or have unexpected values.
- Assertions: Ensure that your test scripts contain valid assertions. For instance, if you’re using
pm.expect(), ensure that it’s correctly set up to test what you intend.
- Pre-Request Scripts: If you have pre-request scripts, make sure they’re not causing requests to be skipped or altered in a way that affects the tests.
- Application Version: Ensure you’re using an up-to-date version of Postman. Occasionally, bugs in older versions can cause unexpected behavior, and updating might resolve the issue.
- Isolated Execution: Try isolating the problematic request and run it individually. This can help determine if the issue is with the specific request’s test scripts or a more widespread problem.
- External Factors: Ensure that there are no network issues, firewall restrictions, or other external factors that might be interfering with the complete execution of your requests and tests.
If, after trying these steps, you’re still facing the issue, it might be helpful to share a sanitized (no sensitive data) version of your collection or a specific request that’s causing problems. This way, others can help replicate the issue and provide more specific guidance.
Hope this helps!
Thanks for your reply, i’m getting the below indication:
Updating environment variables using flows not supported - token_hash.
why its not supported? any way to bypass it?
Ah I think I see the problem now. When using Postman Flows, there are some features and capabilities from the traditional Postman collections and environments that are not directly replicated or may function differently.
The warning “Updating environment variables using flows not supported” is indicating that direct modifications to environment variables, as you would in traditional Postman scripting (using
pm.environment.set() ), are not supported in the same way in Flows.
However, you can still manage and use data across multiple steps in Flows, just in a slightly different manner:
- Capture Data from Responses: In Flows, after making an HTTP request, you can extract data from the response and use it in subsequent steps.
- Use an Evaluate Step: To capture and modify data, you can use the “Evaluate” step. This step allows you to work with the data from the previous step, transform it, and pass it on to subsequent steps. See more including manipulating data on the learning center here.
- Reference Data in Subsequent Steps: Once you’ve transformed and passed data, you can use it in the next steps, including in other HTTP requests.
Regarding bypassing this limitation, you don’t necessarily bypass it but rather adapt to the new Flows paradigm. Instead of trying to update environment variables, focus on passing data between steps using the transform mechanism.
If you rely heavily on modifying and using environment variables in your Postman work, it’s important to note that while Flows provides a new and powerful way to visually manage workflows, there might be scenarios where the traditional Postman collection runner and scripting are more appropriate or familiar. Adjusting to Flows may require a slight shift in approach, but it allows for a more streamlined visual workflow for many use cases.
