Table of Contents

🌩 Installation

npm install karma-jasmine-matchers --save-dev


See the following links for a full list of Matchers and Asymmetric Matchers provided.

🕹 Usage

Just include 'jasmine-matchers' in the frameworks and 'karma-jasmine-matchers'in the plugins section of your config

module.exports = function(config) {
    frameworks: ["jasmine", "jasmine-matchers"],
    files: ["src/**/*.js", "src/**/*.spec.js"],
    // also you must add it as a plugin
    plugins: ["karma-jasmine", "karma-jasmine-matchers"]

TypeScript and Angular CLI projects

If you are using TypeScript, you might want to npm install @types/jasmine-expect --save-dev in order to prevent your IDE from complaining about the new Matchers.

Also, if you run into TypeScript compilation errors when running your tests, add "jasmine-expect" to the "types" array in your tests' tsconfig file.

As an example, for an Angular CLI based project, this would be your tsconfig.spec.json file:

  "extends": "../tsconfig.json",
  "compilerOptions": {
    "outDir": "../out-tsc/spec",
    "baseUrl": "./",
    "module": "commonjs",
    "target": "es5",
    "types": ["jasmine", "node", "jasmine-expect"]
  "files": ["test.ts"],
  "include": ["**/*.spec.ts", "**/*.d.ts"]
