I have the following three tests:

Answered 2022-Jan-06 at 10:34If an exception is thrown inside the Given
or When
block, the test initialisation fails. Here is the output if I run that one test only:
It seems that exceptions are only handled inside the Then
blocks.
This means that everything that can throw an exception should go into Then
blocks, which in turn means that setup and action cannot be shared between the tests:

QUESTION
Long short story: I'd like to publish a variant for jdk8 retro-compatibility for one of my kotlin-only libraries.
This is a long-wanted feature which I'm trying to tackle since quite some time but never got it right. However after many attempts and help on Gradle Slack, I think I'm quite close but I still have an error I can't seem to get rid off.
The idea is to have the main version (src/main
and scr/jpms
, with this latter containing simply module-info.class
) compiled with jdk11, while having a jdk8
variant for src/main
only compiled of course with jdk8.
This is my current build.gradle.kts

QUESTION
I manage an open source project and have a user reporting a situation which I think is impossible according to Java's order of initialization of static variables in classes. The value of a static final
class variable is incorrect, apparently resulting from different results of a dependency's static method based on its own static final variable.
I'd like to understand what's happening in order to figure the best workaround. At the moment, I am baffled.
The problemThe main entry point for my project is the class SystemInfo
which has the following constructor:

Answered 2021-Jul-17 at 00:49DISCLAIMER: I'm writing this as an answer because I don't know how to make it fit into a comment. If it doesn't help you let me know, and I'll delete it.
Let's start with a small recap which given the question quality, I'm sure you're aware of already:
- A field which is
static
to a class, means that it only exists once for any instance. No matter how many instances of the class you create, the field will always point to the same memory address. - A field which is
final
means that once initialized, its value cannot change any longer.
So, when you mix these two into a static final
field, it means:
- You only have one value for that field, no matter how many instances
- Once the value is assigned, it doesn't change any longer
So, my suspect is not that there is any thread-safety issue (I don't think you're running your tests in parallel, so I guess no two-threads would simultaneously work on these objects, right?), but rather that a previous test of your test suite has initialized the variables differently and, being they run into the same JVM, they don't change any longer their values.
Take this very simple test example.
I have one very basic class:

QUESTION
I am trying to publish my Kotlin multiplatform library to Maven Central via Sonatype. This repository requires me to include a javadoc.jar
file with my artifacts. Unfortunately, the IntelliJ IDEA project wizard and the Kotlin multiplatform docs do not help me do that. When running the Gradle task dokkaJavadoc
(for the official Kotlin documentation tool Dokka), I get the error "Dokka Javadoc plugin currently does not support generating documentation for multiplatform project."
I actually do not need genuine JavaDocs for publishing - an empty javadoc.jar
or one with other docs generated by Dokka would suffice. Since I have been a longtime Maven user and these are my first steps with Gradle, I have no idea how to do that.

I noticed I had another issue related to publishing: Signatures and POM information where not applied to all modules. But given Lamba92_v2's code I could resolve all publishing-related issues:

I'm toying around with a small ktor webapp where I want to split functionality in multiple modules. I have a root module where I install the features I want to use throughout the whole application
...ANSWER
Answered 2021-Mar-18 at 07:55Yes, this is a proper way to test an application because modules don't depend on each other and are bound via configuration. Also, instead of adding one more extension method for Application
, you can introduce the following helper function just for testing:
