4 steps to add 🥇KoTest to your Multiplatform project🚀

Kotest is a powerful and flexible testing framework for Kotlin that simplifies the process of writing tests. The framework is designed to be intuitive and expressive, enabling developers to easily define and execute test cases. The quickstart guide provides a comprehensive introduction to getting started with Kotest. It covers essential concepts such as writing test specifications, organizing tests, and leveraging features like property testing. Kotest supports a variety of testing styles, including behavior-driven development (BDD) and property-based testing. The framework’s emphasis on simplicity, combined with its rich set of features, makes it a valuable tool for Kotlin developers looking to create robust and effective test suites for their applications.

🚀Kotest Multiplatform Example:

🚀Run a single test from the commonTest module with the command:

./gradlew :jvmTest --tests DataDrivenTest

🚀Let’s learn how to add KoTest to your Multiplatform Project

🥇1. I’ve created a new project from this Kotlin Multiplatform Wizard for only for iOS and Android development.

🥇2. Add kotest to the project:

🚀File > libs.versions.toml

[versions]
kotest = "5.8.0"
[libraries]
kotest-assertions-core = { module = "io.kotest:kotest-assertions-core", version.ref = "kotest" }
kotest-framework-engine = { module = "io.kotest:kotest-framework-engine", version.ref = "kotest" }
[plugins]
kotestMultiplatform = { id = "io.kotest.multiplatform", version.ref = "kotest" }

🚀File > build.gradle.kts[:main]

alias(libs.plugins.kotestMultiplatform) apply false

🚀File > build.gradle.kts[:shared]

plugins {
    alias(libs.plugins.kotestMultiplatform)
}
sourceSets {
    commonMain.dependencies {
        // put your Multiplatform dependencies here
    }
    
    commonTest.dependencies {
        implementation(libs.kotest.assertions.core)
        implementation(libs.kotest.framework.engine)
        implementation(kotlin("test"))
    }
}

🥇3. Added two tests in separate files in the

:shared:commonTest module:

class FailTest : StringSpec({
    "check app response success test" {
        true shouldBe true
    }
})
class SuccessTest : StringSpec({
    "check app response fail test" {
        true shouldBe false
    }
})

🥇4. Finally run this test with the command:

./gradlew check

🚀Happy Testing ;)🚀
