Hi, please help me with this strange behaviour)
I use testNG, and my lateinit variable is not initialized in @ BeforeSuit

open class BaseTest {
    lateinit var testDataConst: MutableMap<String?,Int?>

    @BeforeSuite
    fun setup() {
        testDataConst = prepareBaseData(conf[system.user],conf[system.password])
        println(testDataConst) <<< here testDataConst is initialized
    }

But in Test class testDataConst is uninitialized

class AddCustomer : BaseTest() {
    @ Test
    fun addCustomer() {
        println(testDataConst)  <<< Here it is an error
    }
}

How could I solve it?

@mike_shysh do you include both classes in your Suite?

[mike_shysh]

I am not using testng.xml at all. Just run all classes with Test annotation as it expected by default

[mike_shysh]

BaseTest class without Test annotation

[cedric]

@mike_shysh Is the BeforeSuite method in your base test class invoked at all?

[mike_shysh]

yes, i have posted a solution brlow the answer

[cedric]

Yes reading the solution

[cedric]

that's weird

[mike_shysh]

static?

[cedric]

Since it's a BeforeSuite, it's fine to put it in a companion object but still

[cedric]

I don't understand why your original code didn't work

[mike_shysh]

its because of testng

[mike_shysh]

testng run beforesuit in separate thread

[cedric]

It should still set that field

[mike_shysh]

thats why we need a static variable

[mike_shysh]

yes, it sets tje field but it is not affected in other threads

[cedric]

Not sure what you mean

[mike_shysh]

for example, if i set the same variable in beforeClass it will work

[mike_shysh]

all my tests in inherited classes, as a result common variable is not visible

[mike_shysh]

with static it work

[mike_shysh]

detailed asnwer requires additional invrstigation) need to dig into testng)
