Hi,
I need to add file on the fly (generate file). What is the most reliable way to do so? I think that generating file to /*out*/test/resources is not a good idea, isn't it?

It doesn’t look related to Kotlin, but maybe you improve your question and give a bit more context

I need a file as a test data. I could create this file at the runtime only. Then I need to use it. What is the best way to do it?

<https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.io/create-temp-file.html>

I think that hardcoded fullpath URL is not a good idea.

it will be saved by default in tmp dir and remove on JVM shutdown

coze I have a lot of files on host machine

also if you use it for test, than it usually responsibility of test to cleanup files and other resources in `@After` method

but `deleteOnExit()` is also fine for most cases

```
    @AfterClass
    fun deleteTestFile(context: ITestContext) {
        val tmpFile: File = context.getAttribute("fileWithEmergencyUnits") as File
        if (tmpFile.exists()) tmpFile.delete()
    }
```

but Thanks for pointing me to deleteonExit i will try

<@U5FFL4V9S> Probably TemporaryFolder test rule is what you need
