Scalameter version 0.4 is out!

[Vlad Ureche]

ScalaMeter 0.4 for Scala 2.10 is now available on maven central!

The centerpiece of this release is HTML reporter based on the D3 visualization library. You can see a live example of the report page here. This new HTML reporter is the default reporter used in PerformanceTest.Regression tests.

Some of its features are:

• x-axis choice for composed generators – allows choosing whether problem size, parallelism level or the measurement date are on the x-axis
• chart and histogram view of the measurements
• confidence interval display
• filtering input parameters interactively
• choosing tests from different test groups interactively
• permalinks that allow sharing the chosen configuration of displayed test groups and input parameters

Other new features include:

• MemoryFootprint measurer allows measuring the memory footprint of a data structure
• -CscopeFilter option allows selectively running only specific tests from your suite
• the include statement for composing several test classes is now more powerful – the enclosing class overrides the persistor and reporter values of the nested test classes, but those tests still use their own executors
• time units now added to regression and logging reporters

Several bugs were fixed for this release: https://github.com/axel22/scalameter/issues?page=1&state=closed
