spek v2.0.14 Release Notes

Release Date: 2020-11-14 // over 3 years ago

  • 🚀 In 2.0.13 discovery and execution started using coroutines, which means they are not confined to a single thread anymore. This can be problematic as most test frameworks like mokk (and possibly mockito) rely on test execution to be confined in a single thread (#923). Another side effect is that the test execution order wasn't deterministic anymore as at any given point a coroutine can be suspended and control is given elsewhere. This release fixes both that issue, Spek is still using coroutines but the runtime ensures that a given test class will always be confined to a single thread.


Previous changes from v2.0.13

  • 🚀 This release adds several system properties to control how Spek does discovery and execution.

    0️⃣ spek2.discovery.parallel.enabled - controls whether discovery is done in parallel or not, by default it is disabled. The presence of this property regardless of value will enable parallel discovery.

    0️⃣ spek2.execution.parallel.enabled - controls whether execution is done in parallel or not, by default it is disabled. The presence of this property regardless of value will enable parallel execution.

    🚚 spek2.execution.test.timeout - SPEK2_TIMEOUT is now deprecated (will be removed in 2.1.0) and will be replaced by this property. Controls how long a test can run before timing out, by default it is disabled - i.e tests won't timeout.

    A note for parallel execution

    ✅ Parallelism is at a class level not individual test scopes. Spek uses coroutines under the hood to execute tests in parallel, essentially spek2.execution.parallel.enabled just controls which CoroutineDispatcher is used. For parallel executions Dispatchers.Default is used, otherwise the one provided by runBlocking is used.
