BREAKING CHANGES

  • core: Stryker now exists with exitCode 1 if an error of any kind occurs.
  • karma-runner: The @stryker-mutator/karma-runner will now use ChromeHeadless by default (instead of PhantomJS)
  • Reporter.onScoreCalculated: Please use the onMutationTestReportReady event and the mutation-testing-metrics npm package to calculate the mutation testing report metrics.

This

class MyReporter {
  onScoreCalculated(scoreResult) {
     // => do stuff with score result
  }
}

Becomes this:

import { calculateMetrics } from 'mutation-testing-metrics';
class MyReporter {
  onMutationTestingReportReady(report){
    const reportMetrics = calculateMetrics(report.files);
    // => do stuff with report metrics
  }
}
  • HtmlReporter: the html reporter is now enabled by default. If you don't want to use it, be sure to override the reporters configuration option.
{
  "reporters": ["progress", "clear-text"]
}
  • Dashboard reporter: The dashboard reporter will now upload a full report by default. If you don't want that, you can disable it with:
{
  "dashboard": {
    "reportType": "mutationScore"
   }
}
  • excludedMutations: removes auto-fix for the old names of mutations.

Migrating:

Almost every mutator has been renamed and/or split. Stryker will warn you about any deprecated mutator names in the mutator.excludedMutations section of your config.

To migrate, please run stryker to see if your project is affected. If this is the case, please take a look at the mutator types on the handbook (see above).

These are the changes:

Old mutation New mutation(s)
ArrayLiteral ArrayDeclaration
ArrayNewExpression ArrayDeclaration
BinaryExpression ArithmeticOperator, EqualityOperator, LogicalOperator
Block BlockStatement
BooleanSubstitution BooleanLiteral
DoStatement ConditionalExpression
ForStatement ConditionalExpression
IfStatement ConditionalExpression
PrefixUnaryExpression UnaryOperator, UpdateOperator, BooleanLiteral
PostfixUnaryExpression UpdateOperator
SwitchCase ConditionalExpression
WhileStatement ConditionalExpression

New mutations

Due to the migration, some new mutations were added to the javascript mutator.

  • The mutation ArrayDeclaration will now mutate new Array() to new Array([])
  • The mutation ArrayDeclaration will now mutate [] to ["Stryker was here"]

These mutations were already performed by the typescript mutator.

  • promisified fs: removed fsAsPromised from @stryker-mutator/util
