PHPUnit Update

Freshly tested every two months: the most important PHPUnit news.

A row of upright, ivory-coloured dominoes with black pips runs diagonally into the depth of the picture, on a dark, glossy surface in which they are reflected. Only the stones in the middle of the row are in focus; those at the front and at the back blur, as does the bright window in the background. A symbol of events that happen in a fixed order, and of seeing sharply the one part that matters right now.

Order and Focus: What is new in PHPUnit 13.4?

Recording the order in which mock objects are invoked, test runs that only load the test files they need, and running the tests you changed last first: I walk you through what is new in PHPUnit 13.4.

Two people running on the red track of a stadium, seen from above, staggered in adjacent lanes. The low sun stretches their shadows far across the surface, and the white lane markings run through the picture at identical spacing. A symbol of running the same course under identical conditions again and again until the pattern becomes visible.

Repetition and Insight: What is new in PHPUnit 13.3?

Reliably detecting flaky tests and tolerating them in a controlled way, code coverage through the lens of your classes, branch and path coverage made visible, and a filter by test size: I walk you through what is new in PHPUnit 13.3.

A hand holds a camera lens up against a deep blue background, its rear glass element and electrical contacts facing the viewer. A symbol of reaching for a precision instrument and choosing exactly where to point it.

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.

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.

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?

The picture shows a beautiful mountain landscape in the morning or evening light. In the foreground, you can see several dark, partly snow-covered ridges, while in the background, gently rolling hills and mountains disappear into the distance on several levels. The scene is shrouded in mist or haze, which enhances the colour gradient from violet to pink to bright yellow and finally blue in the sky. At the bottom right edge, a single person stands on a ridge with a walking stick, giving the image a particularly calm and impressive atmosphere.

More control, less friction: What's new in PHPUnit 12.4?

Discover how PHPUnit 12.4 helps you get there with less friction and more insight.

The image shows several people working together to assemble a puzzle made up of yellow pieces that form the shape of a light bulb. The light bulb typically symbolises an idea or innovation. The scene takes place on a wooden table, which also holds a cup of coffee, a glass of water, an open laptop and some documents. The people's hands are visible as they fit the puzzle pieces together, illustrating collaboration and teamwork.
