Chutzpah 4.0 – Batching, Inheritance and more

Chutzpah 4.0 cleans up some of the legacy baggage while adding the much requested feature of test file batching.

Changes

Test File Batching

Chutzpah has always created an HTML harness for each of your test files. This has the advantage of isolated one test from another but it has the big draw back of limiting throughput of running all your tests. Especially for people with large suite of tests parallel execution of individual test harnesses will not be as fast as batching them all together in one harness. With this release Chutzpah now adds support for both modes. When you set the following in your chutzpah.json file:

"EnableTestFileBatching": true

It tells Chutzpah to put all the test files under this chutzpah.json file into one HTML harness (see full sample). Because the settings file determines the grouping of files that get combined into one harness it gives you the ability to determine what tests you want to get loaded into one harness. Chutzpah can then run those harness in parallel which can give you increased throughput. In the future (based on user feedback) batching may become the default.

 

Settings File Inheritance

The addition of the test file batching feature above encourages the use of multiple chutzpah.json files to help control how files are batched and parallelized. This presents a problem though since your project will often have a set of common files and you would rather not list them multiple times in different settings files. To address this you can now inherit settings from a parent chutzpah.json file. In your chutzpah.json file (see full sample) you write:

"InheritFromParent": true

Which instructs Chutzpah to traverse recursively up the folder hierarchy and look for another chutzpah.json file. If found it will merge the two files and combine their settings. The inheritance between a parent and child settings works as follows when both the parent and child files contain the same setting:

Setting Name What happens?
References References from child template are prepended with the references from the parent template
Templates Templates from the child template are prepended with the templates from the parent template
Tests Not inherited
*All Others* Child template overwrites the parent template setting

 

Multiple Includes/Excludes for Tests and References Settings

The Tests and References settings now have Excludes and Includes properties (in addition to the old singular Exclude and Include setting). The new plural settings let you specify an array of patterns. This provides more flexibility when describing what files you do and do not want to include for a folder. For example:

{
    "Tests": [
        { "Path": "someFolder/someOtherFolder", "Includes": [ "*Dir1/*.js", "*Dir2/*.js"], "Excludes": [ "*Dir1/test4.js", "*Dir2/test2.js" ] }
    ]
}

 

Legacy Compilation Support Removed

The 4.0 release removes the legacy compilation support. Chutzpah no longer ships with a built in TypeScript and CoffeeScript compiler. Please use the compile setting now to configure how Chutzpah handles TypeScript or CoffeeScript files.
