Bug Fixes

Features

BREAKING CHANGES

  • range: The range property is no longer present on a mutant. Note, this is a breaking change for plugin creators only.

Co-authored-by: Simon de Lang simondelang@gmail.com

  • options: "perTest" is now the default value for "coverageAnalysis" when the configured test runner is not "command". Explicitly set "coverageAnalysis": "off" manually to opt-out of this behavior.
  • node: Node 10 is no longer supported. Please use Node 12 or higher.
  • serialize: Having a non-JSON-serializable value in your configuration won't be sent to the child process anymore. If you really need them in your test runner configuration, you should isolate those values and put them in test runner-specific config files, loaded by the test runner plugin itself, for example, jest.config.js, karma.conf.js, webpack.config.js.
  • ignore patterns: Stryker will no longer use a git command to determine which files belong to your project. Instead, it will rely on sane defaults. You can change this behavior by defining ignorePatterns.
  • ignore patterns: The files configuration option is deprecated and will be removed in a future release. Please use ignorePatterns instead.

This:

{
  "files": ["foo.js"]
}

Is equivalent to:

{
  "ignorePatterns": ["**", "!foo.js"]
}

  • excludedMutations: remove deprecated mutation names (#2027) (6f7bfe1)
  • HtmlReporter: include the html reporter in the core package and add it to the default reporters (#2036) (09702d9), closes #1919
  • Initializer: Initialize config file as JSON by default (#2093) (e07d953), closes #2000
  • promisified fs: use node 10 promisified functions (#2028) (1c57d8f)
  • react: change react to create-react-app (#1978) (7f34f28)
  • Reporter.onScoreCalculated: remove deprecated onScoreCalculatedevent (#2026) (9fa4175)

BREAKING CHANGES

  • core: Stryker now exists with exitCode 1 if an error of any kind occurs.
  • 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"]
}
  • 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
