Jest-compact-reporter NPM

Jest Compact Reporter

Fork of Sunfit's jest-summary-reporter. Rewritten in TypeScript with a few additional options.

Motivation

The default Jest reporter output is sometimes too fancy, especially in environments which doesn't support things such as colours etc. This can make the output difficult to read.

This custom reporter will print a more compact form of the information showing only the failed tests by default.

Additional options are available to customise the output. See options.

Examples

Default

default-output

No colours

default-output

Show passing tests

With single test

With multiple tests

Installation

With NPM

npm i -D jest-compact-reporter

With Yarn

Jest Config

No options

// jest.config.js or jest.config.ts
{
  "reporters": ["jest-compact-reporter"]
}

With options

// jest.config.js or jest.config.ts
{
  "reporters": [
      ["jest-compact-reporter", { diffs: true, colours: true, showPassingTests: false }]
    ]
}

Options

diffs

Defaults to true. If enabled prints Jest's default error explanations for each failing test.

colours

Defaults to true. If enabled adds colours to the output for improved readability. Disable when an environment doesn't support colours.

showPassingTests

Defaults to false. If enabled shows test names of passing tests as well rather than just the suite.
