Testing

When you’re ready to test changes to your Force.com app source code, you can run Apex tests from the Salesforce DX CLI. The command runs Apex tests in your scratch org.

You can also execute the CLI command for running Apex tests (force:apex:test:run) from within third-party continuous integration tools, such as Jenkins.

To run Apex tests from the command line:

This command runs all Apex tests in the scratch org asynchronously and then outputs a job ID. Pass the ID to the force:apex:test:report command to view the results. The results include the outcome of individual tests, how long each test ran, and the overall pass and fail rate.

Use the --resultformat parameter to run the tests synchronously. The command waits to display the test results until all tests have completed.

Use parameters to list the test classes or suites to run, specify the output format, view code coverage results, and more. For example, the following command runs the TestA and TestB tests, provides results in Test Anything Protocol (TAP) format, and requests code coverage results.
