Bug Report

When I have return require('dd-trace/ci/cypress/plugin')(on, config); in config, my events are not firing. Whenever I return just the config, events are firing as expected.

Hi @mekhron, are you trying to run your tests in interactive mode? If so, we have a Known limitation for that type of case (Docs Datadog). If not, could you share a bit more info about how you're running the tests?

[mekhron]

@Mariovido I am running either way. My before:run event is not firing even when I run in headless mode.

Here are the vents I have in cypress.config.js:

            on('before:run', () => {
                console.log('BEFORE RUN');
            });

            on('after:run', (details) => {
                console.log('AFTER RUN');
                // other 'after:run' handlers
                // important that this function call is returned
                return require('dd-trace/ci/cypress/after-run')(details);
            });

            on('after:spec', (...args) => {
                console.log('BEFORE SPEC');
                // other 'after:spec' handlers
                // Important that this function call is returned
                // Important that all the arguments are passed
                return require('dd-trace/ci/cypress/after-spec')(...args);
            });

So the dd-trace events are firing fine (after:run and after:spec), but the before:run is not logging anything.

Here is the command how I run: npx cypress run -e ENVIRONMENT=qa.

Thanks for taking a look at this.

@mekhron I tried reproducing your case and I am able to log it (cypress run):

Code sample

module.exports = defineConfig({
  e2e: {
    setupNodeEvents(on, config) {
      require("dd-trace/ci/cypress/plugin")(on, config);
      on("before:run", () => {
        console.log("BEFORE RUN");
      });
      // other plugins
      on("after:run", (details) => {
        console.log("AFTER RUN");
        // other 'after:run' handlers
        // important that this function call is returned
        return require("dd-trace/ci/cypress/after-run")(details);
      });
      on("after:spec", (...args) => {
        console.log("AFTER SPEC");
        // other 'after:spec' handlers
        // Important that this function call is returned
        // Important that all the arguments are passed
        return require("dd-trace/ci/cypress/after-spec")(...args);
      });
    },
    supportFile: "cypress/support/e2e.js",
  },
});

Which Cypress version are you using?

[mekhron]

@Mariovido 14.2.1

[Mariovido]

@mekhron I tried with that version and it worked. Let's do one thing, could you reach out to support to be able to share your logs? Mainly what I would like to see after is:

• The tests running with DD_TRACE_DEBUG=1
• Your cypress.config.js and support.js files and other configuration that may be interfering with the tests (removing sensitive info)
• Snippet where the command is being run (GitHub Job,...)
