Fixtures for the OS, JRE, system property, environment variable and EnabledIf conditions plus a custom ExecutionCondition, run through the JUnit Platform launcher (in-process and in child JVMs) to capture real skip reasons; skipped versus aborted lifecycle; stacking, class-level skips and the deactivate switch; the 2025 article's code compiled as published; and a javap comparison of the condition package in 5.14.4 and 6.1.3.
