  Karate 2.0.0

  🚀 The first major release of Karate v2 — a ground-up rewrite of the test automation framework, built on Java 21+ virtual threads with a custom JavaScript engine.

  Highlights

  • Custom JS Engine — embedded JavaScript engine (karate-js) replaces GraalJS. Minimal external dependencies, faster startup, native Java interop
  • Virtual Threads — parallel test execution on Java 21+ virtual threads. No thread pool tuning needed
  • W3C WebDriver — full cross-browser support for Chrome, Firefox, Safari, and Edge alongside the existing CDP driver
  • 💻 Browser Pooling — automatic browser instance reuse across parallel scenarios via PooledDriverProvider
  • Karate CLI — single binary launcher, no Maven or Gradle required. Install from VS Code with one click:

  📄

  • Rewritten CDP Driver — auto-wait, Shadow DOM support, smarter element location
  • Gatling Integration — Java-only DSL for load testing (karateProtocol(), karateFeature())
  • Interactive HTML Reports — Alpine.js dashboard with timeline view, tag filtering, and nested call display
  • Declarative Auth — configure auth for Basic, Bearer, and OAuth2 with automatic token refresh
  • Soft Assertions — All JSON errors collected instead of first assertion failure. continueOnStepFailure mode for features
  • Built-in Utilities — karate.faker.* for test data, karate.expect() for Chai-style assertions

• v1.5.0 Changes

  August 05, 2024

  💥 Breaking Changes

  • Karate 1.5.0 requires Java 17
  • The Maven group-id has changed from com.intuit.karate to io.karatelabs

  🏗 So the only change should be to your pom.xml or gradle.build.

  There are no other syntax or behavior breaking changes, so this should be a smooth upgrade for your tests. The Java APIs (package names) have not changed. They will change only in a future release (most likely 1.6.0).

  Notable Improvements

  • 👍 Support for Java 22+
  • CVE resolutions
  • 👀 Java DSL for Gatling - see example
  • 👍 Playwright Support

• v1.5.0.RC5 Changes

  July 26, 2024

  🚀 Karate 1.5.0 will require Java 17. Karate 1.5.0 will also change the Maven group-id from com.intuit.karate to io.karatelabs. For a smoother transition, the Java APIs would be changed in a future release (most likely 1.6.0). Karate 1.5.0 is required if you use Java 22 or greater.

  🚀 This is an RC release, so there could be minor changes before 1.5.0 (final). But most teams can start using this, especially those who need Java 17 and the CVE resolutions.

  Notable Improvements

  • CVE resolution
  • 👀 Java DSL for Gatling - see example

  🛠 Fix List

  Some notable improvements:

  • 👀 UI testing - driver.intercept() (Chrome only) now returns a mock, which opens up some advanced use-cases, see #2361
  • 👀 some teams reported a slow down in Karate 1.4.0 especially when a lot of JS re-use was involved, which should be fixed, see #2329

  🚀 Here is a complete list of all issues fixed in this release.

  💥 Breaking Changes

  ✅ The good news is that for most teams there should not be any breakages to existing test scripts. But there are a few things to note, read on below.

  0️⃣ match each defaults to fail if array is empty

  👀 You can read a detailed description in the issue #2364. This may break existing test scripts only if you are extensively using the fuzzy matching short-cut #[] in enbedded schema validations. The good news is that if you see any of your existing tests break, you can do this to get back the old behavior.

  \* configure matchEachEmptyAllowed = true
  

  if a match each fails now with Karate 1.4.1, ensure that any JsonPath expression on the LHS (Left Hand Side) is accurate. The reason for this change in Karate behavior is that previously - if you had an invalid JsonPath expression on the LHS of a match each, it would always return an empty array, and the match would always pass.

  🐳 Docker image now in karatelabs organization

  🐳 Until now, the karate-chrome Docker image was published at ptrthomas/karate-chrome. It has now moved to karatelabs/karate-chrome.

  IDE debugging requires extra dependency

  IDE debugging now requires an extra dependency on the classpath. Maven and Gradle users can use the io.karatelabs:karate-debugserver dependency. For details on how to use the new debug-server in IntelliJ or VS Code, please refer to this wiki page: Debug Server.

  🚚 Experimental Distributed Testing Support Removed

  🚀 Karate used to have a distributed-testing (experimental) option released in v0.9.5. This is no-longer available as part of karate-core

  Heads Up

  🚀 Karate 1.5.0 will require Java 17. This is a bit sooner than we expected, but reasons are explained in #2401 - mainly because of needing to address some CVEs. 1.4.1 may be the last release that supports Java 11.

  🚀 Karate 1.5.0 will also change the Maven group-id from com.intuit.karate to io.karatelabs. Note that a 1.5.0.RC1 is available for teams to start trying this out. For a smoother transition, the Java APIs would be changed in a future release (most likely 1.6.0).

• v1.4.0 Changes

  April 02, 2023

  Important

  ⬆️ There are multiple security vulnerabilities in libraries that Karate depends on that are fixed in this release. If you are on an old version of Karate - it is strongly recommended that you upgrade. Refer #2148 | #2265 | #2277

  💥 Breaking Changes

  The main change in this release is that Karate requires Java 11 or above. We no longer support Java 8. Otherwise there should not be any syntax or behavior changes (from Karate 1.3.X).

  Note that some of the security / CVE fixes cannot be back-ported to Java 8 because they depend on Java 11.

  Also note:

  • 🚚 JUnit 4 is no longer supported. If you were using JUnit 4, either move to the Runner API or JUnit 5
  • 🚀 The ZIP release is no longer published since the official Karate plugins provide a better quick-start experience. The stand-alone JAR is still available.
  • 🤡 The karate-mock-servlet dependency is no longer published
  • The old cucumber-java 1.2.5 dependency is no longer included, refer #2214

  🚀 Here is a complete list of all issues fixed in this release.
