Can't use a common name in different nested classes

[arekolek]

This code

@Fixture
data class Foo(val baz: Baz) {
    @Fixture
    data class Baz(val text: String)
}

@Fixture
data class Bar(val baz: Baz) {
    @Fixture
    data class Baz(val number: Int)
}

produces an error because of Baz:

@arekolek Thank you for your feedback! :) This is something that we did not take into account. We will implement a solution though and release a version.

[arekolek]

@St4B I see fix is merged, but is it released?

[St4B]

@arekolek We have released an alpha version (1.0.8-alpha01). There might be some breaking changes.

From now on, if a file contains multiple classes annotated with @Fixture, then the generated functions will be placed in a single file. (Previously we created a file for every generated function).

Additionally, for inner classes, the naming convention is to use the outer class name too. In your example, two functions will be created:

• createFooBaz()
• createBarBaz()
