Seamlessly use the power of Karate from Node / JS projects.
Given this script test.js:
#! /usr/bin/env node
const karate = require('@karatelabs/karate');
karate.exec();And in package.json (use the latest version from npm):
{
"scripts": {
"test": "node test.js"
},
"devDependencies": {
"@karatelabs/karate": "^0.2.2"
}
}When you run npm install, jbang and other Karate dependencies needed will be installed via jbang-npm.
And to run a single test:
npm run test karate/httpbin.feature
Or to run all tests in a folder:
npm run test karate
Users on Windows have reported issues such as the npm install failing to complete and without any errors shown.
Please do contribute if you can and improve how JavaScript projects can integrate smoothly with Java projects !
As a workaround, please install JBang manually and re-try the npm install step.
To use a specific version of Karate, just set karate.version before calling karate.exec():
#! /usr/bin/env node
const karate = require('@karatelabs/karate');
karate.version = '1.5.0';
karate.exec();All Karate capabilities can be invoked by the command-line.
The most common needs are to:
- run feature-file(s) or all feature-files in a folder as Karate tests
- start an API mock-server
The complete documentation can be found here.
You can also use the --help command-line option to see all the possible options and brief descriptions on the console.
Karate will look for a karate-config.js file in the current working directory.
But if you need to point to a different directory, you can set karate.config.dir before calling karate.exec()
To pass arguments to the JVM use the jvm object karate.jvm.args
CLI options can be passed as a string to the karate.exec('-T=5') method.
#! /usr/bin/env node
const karate = require('@karatelabs/karate');
karate.config.dir = '/users/myname/some/dir';
karate.jvm.args = `-Dlogback.configurationFile=${__dirname}/logback-test.xml`;
karate.exec("-T=5");For teams that want to customize the Java classpath by adding libraries or custom-code, please refer to the wiki: Custom Fat JAR. This may be easier to achieve by using Maven to prepare a Docker image, which can then be used by teams on the command-line without needing NPM, Java or Karate - and only Docker is a pre-requisite.
If you want to use additional Java libraries or custom code and avoid Maven and Java dev-tools, refer to this example: Using Java Libraries with NPM.
