I'm not sure if this is really related to Kotest. This piece of code I see in every kotlin project

Hello guys, If I found inconsistency in idea code analysis for

kotlin-test

library, where should I put a ticket or at least check for the ticket? Thank you 🙂

4.0.3 has been released

Hi. I just started using Kotest and have an odd use case. I'd like to be able to execute all tests in the same test class multiple times. I am using it for mobile automation with Appium. I need to run the same set of tests for multiple languages. There is a significant setup time starting the driver and connecting to the Appium server. I want to do that once for each language. Then I need to run all the tests. Is there a way to accomplish that with Kotest or a better way to structure my tests so that I can do what I need?

Hey, I am not able to run individual tests on IDEA. It always runs all the test cases in the spec.

Hi I'm migrating from kotlintest to kotest but I found a strange issue: When I run the tests from the

IDE

every test is successful but when I try to run the test with

gradlew

I'm getting this error in an assertion:

java.lang.NoClassDefFoundError: arrow/core/NonFatal

the assertion is this

shouldBeLeft()

Someone can help me?

What’s the state of IntelliJ plugin for kotest 4.0? I see https://github.com/kotest/kotest-intellij-plugin/issues/42 and I’m not sure if it’s worth upgrading right now or I should wait a bit, if IJ (AS) support is important for me

Hey 👋 I saw that experimental Robolectric support was added in September: https://github.com/kotest/kotest/issues/926. It's been a while, has anybody migrated to Kotest with lots of Roblectric tests? Are there any known caveats or is it basically good to go? Thanks! 🙂

anyone having issue on performance ? I’m using kotlin-test 3.3.1 and it takes 3 minutes to compile my test project. and each time I change an individual test case it still take tens of seconds to compile

Anyone got any tips for debugging kotest + dependency issues? I've got an existing project using kotest 4.0.3, but when I add the following line to my build.gradle, non of my tests are getting run (with ./gradlew clean test): • implementation 'com.github.thake.avro4k:avro4k-kafka-serializer:0.2.0' I'm assuming its pulling in a dep that breaks kotest in some way, but can't figure out what, any advice would be really useful!

yeah - it's very nully as it stands. Those are great ideas, thanks, I'll have a play tomorrow.

Intellij plugin 0.90.16 has been released. This is still beta, but if you want to have a go, here it is. Make sure you read the instructions here as this requires a snapshot build of kotest. https://github.com/kotest/kotest-intellij-plugin/blob/master/README.md

Anyone saw this error when trying to run property-based test using generic types?

java.lang.ClassCastException: java.base/sun.reflect.generics.reflectiveObjects.ParameterizedTypeImpl cannot be cast to java.base/java.lang.Class

Is there an easy way to skip a whole test class based on an environment variable? I looked at SkipTestException but it doesn't seem to be available anymore (Docs might need to be updated).

Am I doing something wrong? I'm using kotest

4.0.4

with Arrow's

Either

type to compare two lefts:

val expected = Left(
        <http://java.io|java.io>.FileNotFoundException(
                "data/monkeywrench.txt (No such file or directory)"
        )
)

val result = loadShortCircuit(filePaths) // returns Arrow Left type in this example (see video)

val left = Left(<http://java.io|java.io>.FileNotFoundException("data/monkeywrench.txt (No such file or directory)"))

expected shouldBe left

expected shouldBe left

fails in this case. The equality fails.

hello, did anyone notice failing tests being reported more than once?

package xxx

import io.kotest.core.spec.style.StringSpec
import io.kotest.matchers.shouldBe

class FailingTest : StringSpec() {
  init {
    "reported twice" {
      "a" shouldBe "b"
    }
  }
}

both intellij and gradle reports 2 failure. I scanned open issues and saw nothing, in case I can open one

if I only want to use kotest assertions in a jvm project, which dependencies should I include?

Is this familiar to anyone ?

Hi I've decided to take a deep dive into kotest property-testing and stuck a little bit. I want to write a simple property test for Two Sum problem, so I need to generate random

IntArray

and

Int

that will be sum of two random elements of the generated array. I had no problems with the first Arb:

Arb.list(<http://Arb.int|Arb.int>()).map { it.toIntArray() }

but couldn't find a solution for the second one. Could someone advise something or I choose the wrong direction?

You mean it calls it MyClassKtTest ?

Another observation, when I wish to run only a specific test (say in StringSpec) and when the test-runner is set as Gradle in intellij, it runs all the tests in the file, as the gradle command that triggers is

gradle test --tests "com.package.testClassName"'

. Is this expected?

Is the kotest plugin already use-able? I was trying it out today, I’ve been using kotest in a new project. I shared my gradle config, I also tried with

test { useJUnitPlatform() }

but that didn’t change anything. I have plugin version

3.3.0.11

which I installed from the link on the github page of the plugin. The plugin is also still named

KotlinTest

in my editor, it was called Kotest on the plugin website. Any ideas? Shall I open a ticket on the plugin page? IntelliJ IDEA 2020.1 (Community Edition) Build #IC-201.6668.121, built on April 8, 2020 Runtime version: 11.0.6+8-b765.25 x86_64 VM: OpenJDK 64-Bit Server VM by JetBrains s.r.o macOS 10.15.4 GC: ParNew, ConcurrentMarkSweep Memory: 4012M Cores: 12 Registry: ide.balloon.shadow.size=0 Non-Bundled Plugins: org.intellij.scala, org.jetbrains.kotlin, kotlintest-plugin-intellij

I remember suspending forAll was available in kotest. Any chance I am looking in the wrong modules or packages?

Hi, is there any reason why an application cannot startup if it does an

implementation

instead of

testImplementation

of the kotlintest dependency? I.e. when I do

testImplementation("io.kotlintest:kotlintest-runner-junit5:3.4.2")

I have no issues, however when I do

implementation("io.kotlintest:kotlintest-runner-junit5:3.4.2")

I get this error when running my bundled jar:

Error: Could not find or load main class package.ApplicationKt
Caused by: java.lang.ClassNotFoundException: package.ApplicationKt

Damn,

choose

constrains to

Any

😄
