Sharded Cypress Example

Testkube has built-in support for parallelizing any testing tool - check out the Parallelization documentation for details and examples.

The below example shows how to distribute ("shard") a set of Cypress tests across a configurable number of nodes.

The example below:

• Loads the Cypress tests from the Git repository (content).
• Sets the working directory to the tests one (container.workingDir).
• Installs the project dependencies (steps[0].shell).
• Runs Cypress tests with dynamic sharding (steps[1].parallel).
  • The shards will be built off the test files in cypress/e2e directory (steps[1].parallel.shards.testFiles).
  • It will have maximum of 5 shards (steps[1].parallel.maxCount).
    • When there is less than or equal to 5 test files, it will run 1 shard per test file.
    • When there will be more than 5 test files, it will distribute them across 5 shards.
  • Each shard will run only selected test files with --spec Cypress' argument (steps[1].parallel.run.args).
