UI CoveragePremium Solution

Results API

The @cypress/extract-cloud-results module provides the getUICoverageResults utility to programmatically fetch UI Coverage results for a run in a CI environment. This allows you to determine if test coverage meets your requirements before merging code changes.

Supported CI Providers​

The utility supports the following CI providers. Refer to the linked guides for setup details:

For other CI providers, contact Cypress Support to request support.

Installation​

Install the @cypress/extract-cloud-results module in your install step in CI.

npm install --force https://cdn.cypress.io/extract-cloud-results/v1/extract-cloud-results.tgz
caution

Do not check this module in as a dependency. We recommend you install it separately outside of your normal module installation. Use --force to get the latest version.

If you check this in as a dependency, your installation will fail when we update the package.

Usage​

1. Get the UI Coverage Results​

Write a script to fetch UI Coverage results and assert test coverage criteria. This script will be executed in CI.

scripts/verifyUICoverageResults.js
const { getUICoverageResults } = require('@cypress/extract-cloud-results')

getUICoverageResults({
  projectId: process.env.CYPRESS_PROJECT_ID, // Optional if set from env
  recordKey: process.env.CYPRESS_RECORD_KEY, // Optional if set from env
  runTags: [process.env.RUN_TAGS], // Required if recording multiple runs
}).then((results) => {
  const { runNumber, uiCoverageReportUrl, summary, views } = results

  console.log(
    `Received ${summary.isPartialReport ? 'partial' : ''} results for run #${runNumber}.`
  )
  console.log(`See full report at ${uiCoverageReportUrl}.`)

  // Verify overall coverage
  if (summary.coverage < 80) {
    throw new Error(
      `Project coverage is ${summary.coverage}, below the minimum threshold of 80%.`
    )
  }

  const criticalViews = [/login/, /checkout/]

  // Verify critical view coverage
  views.forEach((view) => {
    const { displayName, coverage, uiCoverageReportUrl } = view

    if (
      criticalViews.some((pattern) => pattern.test(displayName)) &&
      coverage < 95
    ) {
      throw new Error(
        `Critical view "${displayName}" coverage is ${coverage}%, below the required 95%. See: ${uiCoverageReportUrl}`
      )
    }
  })

  console.log('UI Coverage is above minimum thresholds.')
})

getUICoverageResults arguments​

getUICoverageResults accpets the following arguments:

getUICoverageResults({
  // The Cypress project ID.
  // Optional if the CYPRESS_PROJECT_ID env is set
  projectId: string
  // The project's record key.
  // Optional if the CYPRESS_RECORD_KEY env is set
  recordKey: string
  // The run tags associated with the run.
  // Required IF you are recording multiple Cypress runs from a single CI build.
  // Pass the run tags you used when recording in each run
  runTags: string[]
})

Result Details​

The getUICoverageResults utility returns the following data:

{
  // The run number of the identified build.
  runNumber: number
  // The run url for the identified build.
  runUrl: 'https://cloud.cypress.io/projects/:project_id/runs/:run_number'
  // The status of the identified build.
  runStatus: 'passed' | 'failed' | 'errored' | 'timedOut' | 'cancelled' | 'noTests'
   // The url that links to UI Coverage report for the identified build.
  uiCoverageReportUrl: 'https://cloud.cypress.io/[...]'
  summary: {
    // Indicates whether a complete UI Coverage report was generated.
    // For example, if a run was cancelled and the report expected to run
    // for 20 specs, but only 10 ran, this would result in a partial report.
    isPartialReport: boolean
    // The report coverage from 0-100 with 2 decimal precision (e.g 92.45).
    coverage: number
    // The number of views tested and analyzed.
    viewCount: number
    // The number of interactive elements that were tested.
    testedElementsCount:number
    // The number of interactive elements that were not tested.
    untestedElementsCount: number
  }
  // The list of tested views and the coverage of each page.
  views: [{
    // The sanatized URL pattern shown in the report.
    displayName: string
    // The view coverage from 0-100 with 2 decimal precision (e.g 92.45).
    coverage: number
    // The number of interactive elements that were tested on this view.
    testedElementsCount:number
    // The number of interactive elements that were not tested on this view.
    untestedElementsCount: number
    // The url that links the report for this view.
    uiCoverageReportUrl: 'https://cloud.cypress.io/[...]'
  }]
}

2. Add to CI Workflow​

In your CI workflow that runs your Cypress tests,

  1. Update your install job to install the @cypress/extract-cloud-results module.
  2. Pass in the necessary arguments to getUICoverageResults.
  3. Add a new step to the job that runs your Cypress tests to verify the UI Coverage results.
info

If you record multiple runs in a single CI build, you must record these runs using the --tag parameter and then call getUICoverageResults with the runTags argument for each run.

This is necessary to identify each unique run and return a corresponding set of results. The tags are how each run is uniquely identified.

Example

  • Let's imagine that within a single CI build you call cypress run --record multiple times because you're running one set of tests against a staging environment, followed by a production environment.
  • In this scenario, you pass a different --tag to each cypress run
    • cypress run --record --tag staging
    • cypress run --record --tag production
  • When calling getUICoverageResults you would then pass these same tags to get the unique set of results for each run
    • getUICoverageResults({ runTags: ['staging']})
    • getUICoverageResults({ runTags: ['production']})
