Postman – Testmo

Testmo works with any test automation tool, including the Postman API testing platform. This quickstart guide provides an overview of how to report Postman test automation results to Testmo.

Run Postman & generate XML file

Postman comes with full support for generating JUnit-style XML files, which has become a standard format to exchange test results between tools.

$ newman run collection.json -r cli,junit --reporter-junit-export results/test-results.xml

This will run your tests with Postman and automatically write all test results to an XML file in the results directory. You can also use any additional standard newman command line argument and you can learn more about the built-in junit formatter in the Postman documentation.

Submit test results to Testmo

To submit your test results to Testmo, you simply use our cross-platform testmo CLI tool. The CLI tool is distributed as an NPM package and is easy to install on any system. Simply install our official @testmo/testmo-cli NPM package:

$ npm install -g @testmo/testmo-cli
$ testmo -h

Usage: testmo [options] [command]
[...]

We can now send the Postman test results to Testmo. To do this, make sure to generate an API key in Testmo from your profile page. The API key is used to authenticate with Testmo to send the results. We can then use the testmo CLI tool so submit our results (note that we first set the TESTMO_TOKEN variable, which the tool expects):

Full example

Single line

Windows

$ export TESTMO_TOKEN=********
$ testmo automation:run:submit \
  --instance https://<your-name>.testmo.net \
  --project-id 1 \
  --name "Postman test run" \
  --source "api" \
  --results results/*.xml

If you run this example on a single command line, make sure to remove the backspace:

$ export TESTMO_TOKEN=********
$ testmo automation:run:submit --instance https://<your-name>.testmo.net --project-id 1 --name "Postman test run" --source "api" --results results/*.xml

On Windows, the command line uses a slightly different syntax to set a variable:

> set TESTMO_TOKEN=********
> testmo automation:run:submit --instance https://<your-name>.testmo.net --project-id 1 --name "Postman test run" --source "api" --results results/*.xml

See command output

Collecting log files ..
Found 1 result file with a total of 855 tests
Created new automation run (ID: 254)
Created new thread (ID: 608)
Sending tests to Testmo ..
Uploading: [|||||||||||||||||||||||||] 100% | ETA: 0s | 855/855 tests
Successfully sent tests and completed run
Marked the run as completed

That's it! 🎉 This will automatically analyze the XML result file, create a new test run in Testmo, submit all tests & results and mark the run as completed. There's no need to manually create any tests, map tests or IDs or build any custom API code. Everything is handled automatically for you.

➡️ Bonus: Launch Postman with Testmo CLI

In the above example, we first launched Postman to generate the XML file and then used our CLI tool to submit the results in a second step. As an improvement to the above example, we can ask our CLI tool to launch Postman (testmo then starts and waits for Postman to finish). This has the following additional benefits:

a) Capture full console output and send it to Testmo

b) Accurately measure test times

c) Record the Postman exit code

Launch Postman with CLI tool

We can ask our CLI tool to launch Postman, so we can capture the console output and more:

$ export TESTMO_TOKEN=********
$ testmo automation:run:submit \
  --instance https://<your-name>.testmo.net \
  --project-id 1 \
  --name "Postman test run" \
  --source "api" \
  --results results/*.xml \
  -- newman run collection.json -r cli,junit --reporter-junit-export results/test-results.xml
    ^ space!
