Use Nextest - Githubissues

IMO it targets many of the issues we are currently having with tests in CI.

Features:

Clean, beautiful user interface. Nextest presents its results concisely so you can see which tests passed and failed at a glance.

Up to 3× as fast as cargo test. Nextest uses a state-of-the-art execution model for faster, more reliable test runs.

Identify slow and leaky tests. Use nextest to detect misbehaving tests, identify bottlenecks during test execution, and optionally terminate tests if they take too long.

Filter tests using an embedded language. Use powerful filtersets to specify granular subsets of tests on the command-line, and to enable per-test overrides.

Configure per-test settings. Automatically retry subsets of tests, mark them as heavy, or run them serially.

Designed for CI. Nextest addresses real-world pain points in continuous integration scenarios:

Use pre-built binaries for quick installation.

Set up CI-specific configuration profiles.

Reuse builds and partition test runs across multiple CI jobs. (Check out this example on GitHub Actions).

Automatically retry failing tests, and mark them as flaky if they pass later.

Print failing output at the end of test runs.

Output information about test runs as JUnit XML, and in other formats.
