Strikt

Strikt is an assertion library for Kotlin intended for use with a test runner such as JUnit, Minutest, Spek, or KotlinTest.

Strikt uses a fluent assertion style similar to AssertJ but leverages Kotlin's type system and extension functions rather than needing a complex hierarchy of assertion builder classes.

Strikt is under development, but 100% usable. The API may change until a version 1.0 is released. Any suggestions, issue reports, contributions, or feedback are very welcome.

Installation

Strikt is available from Maven Central.

repositories {
  mavenCentral()
}

dependencies {
  testImplementation("io.strikt:strikt-core:<version>")
}

See the button below or releases/latest for the current version number.

Additional Libraries

Strikt has the following additional libraries:

• strikt-arrow -- supports data types from the Arrow functional programming library.
• strikt-jackson -- supports the Jackson JSON library.
• strikt-jvm -- supports types from the Java SDK.
• strikt-mockk -- supports types from the MockK library.
• strikt-protobuf -- supports Protobuf / gRPC.
• strikt-spring -- supports the Spring Framework.

Versions are synchronized with the core Strikt library.

To install additional libraries include dependencies in your Gradle build. For example:

dependencies {
  testImplementation("io.strikt:strikt-jvm:<version>")
}

Bill of Materials

Strikt supplies a BOM that is useful for aligning versions when using more than one Strikt module.

dependencies {
  // BOM dependency
  testImplementation(platform("io.strikt:strikt-bom:<version>"))

  // Versions can be omitted as they are supplied by the BOM
  testImplementation("io.strikt:strikt-jackson")
  testImplementation("io.strikt:strikt-jvm")
  testImplementation("io.strikt:strikt-spring")
}

Using Strikt
