Precision and Clarity: What is new in PHPUnit 13.2?

Selecting exactly the tests you want, finer control over the order they run in, faster and clearer output when they fail, and more expressive test doubles: I walk you through what is new in PHPUnit 13.2.

Merging code coverage data

Merging code coverage data from parallel CI jobs has long been fragile and error-prone. These problems are finally solved.

A glowing cockpit instrument panel in deep blue light, its dials, throttle levers, and backlit gauges tracing speed and status: a metaphor for reading the telemetry your test suite records on every run.

What your test run already knows

On every run, PHPUnit knows how long each test took, how much memory it used, and why it failed. Most of that evaporates. otr-report reads it back out of the Open Test Reporting logfile and puts it within reach.

Turbo-Charging Your PHPUnit Suite

Slow tests destroy flow, kill TDD, and erode trust until nobody runs the suite. The fix has four tiers, and the biggest wins come from test design, not from infrastructure or parallelisation.

Closures, Clarity, and Control: What is New in PHPUnit 13.1?

Closures as data providers, richer Open Test Reporting, custom issue trigger resolvers, and significant changes to code coverage: I walk you through the changes.

From anti-pattern to clarity

The any() matcher is deprecated. But migration is easier than you think – and leads to better tests.

Better than withConsecutive()

I explain how PHPUnit 13's parameter set matchers finally solve the problem that made upgrading to PHPUnit 10 such a challenge.

This image depicts a woman holding a white theatrical mask up to her face against a dramatic, dark background. A bold red panel is visible on the left, and there is ambient stage lighting in the background, consisting of blue and white orbs. Her eyes peer over the mask, suggesting a moment of self-examination or realisation, with an expression of curiosity and slight concern. The theatrical setting and professional staging emphasise the performative nature of the moment.

The Stub/Mock Intervention

Self-sabotaging mock objects? With PHPUnit 12.5, that's a thing of the past because the test runner now asks the right question: Do you really need a mock object, or would a test stub suffice?
