Support for NO_COMMAND_LOG env variable not implemented

[sync-by-unito]

The NO_COMMAND_LOG env variable can be used in Cypress 9.x to disable rendering of the command log; see the troubleshooting guide for user-facing info.

We should support similar functionality to this in 10.0.

➤ Zach Williams commented:

NO_COMMAND_LOG is passed via the cypress config, we could pull this value and conditionally render the reporter in packages/reporter/src/main.tsx

Noting that we have a skipped spec that can be enabled with the completion of this work:

cypress/packages/app/cypress/e2e/runner/runner.ui.cy.ts

Lines 233 to 242 in 92eac2f

	it.skip('supports disabling command log reporter with env var NO_COMMAND_LOG', () => {
	loadSpec({
	fileName: 'disabled-command-log.runner.cy.js',
	passCount: 0,
	failCount: 0,
	})
	cy.get('.reporter').should('not.exist')
	})
	})

When adding this support, we need to ensure the command log doesn't take up space in the UI as reported as a previous regression in #21271

Can we please get this feature back in v10? Enabling it drastically reduces the overall time whilst running the tests headless so it could even be prioritized higher.

I can live without the detail in the test screenshots/video if the tests runs twice as fast.
I dont really want to revert to an earlier version as I have just gone through the pain of migrating the build process to v10

[vergjor]

honestly the lack of this feature is preventing me to migrate to version 10 of cypress, since it has a major influence on our test execution, I really hope this is implemented as soon as possible

@pmcochrane @vergjor I ran across the skipped test for this yesterday which led me to this issue, I've opened a PR and it should make it in to a release pretty soon.
