Goal: Writing more readable tests.



I have a couple of functions, which basically merge and converts two lists of Datasets together, written using Scala and Spark. Each of these Datasets has a lot of fields inside it. For testing, I'm creating three Datasets: New records, existing records, and expected result.



The problem is, tests are long and hard to read. An example:



test("Merging Movies") {

val newMovies: Dataset[ATMMovie] = Seq(
ATMMovie(
id = 123L,
utc_insert_timestamp = Some(1524522274),
movie_title = Some("New movie from ATM"),

As you see, each test is very hard to read and follow. I'm looking to find a better way to write these tests.



Update: I don't care about the value of most of the fields. I'm going to test the logic of merging.

Without seeing the code that performs this "merging" I find it hard to tell what's going on in here. Without understanding what are you testing, it's hard to suggest improvements for the tests.

My team and I typically find that having a "defaults" file in our API test package to be very useful when writing data-oriented tests. If these domain objects need to be used in future, we can rely on the fact that they're determinstic and centralized.

Our best solution to his was to use a generator-like class or function.



val newMovies = DataFrameBuilder().add(1).add(2)


It generates values for fields based on the number we provide. If type is a number, value will become the number itself. If it's a string, value will become name of the field plus the number (e.g. MOVIE_TITLE 1)



Another solution was to use a function that takes some of the fields we care about, and fills the rest with constant values. Like, it takes id and utc_insert_timestamp, and fills everything e
