I think we can just throw all of the tests in expr.test
This is what we are doing with other ones. (testing series + expr) at the same time
example:
test("contains:regex", () => {
const df = pl.DataFrame({
a: ["Foo", "foo", "FoO"],
});
const re = new RegExp("foo", "i");
const expected = pl.DataFrame({
a: ["Foo", "foo", "FoO"],
contains: [true, true, true],
});
const seriesActual = df.getColumn("a").str.contains(re).rename("contains");
const actual = df.withColumn(col("a").str.contains(re).as("contains"));
expect(actual).toFrameEqual(expected);
expect(seriesActual).toSeriesEqual(expected.getColumn("contains"));
});There was a problem hiding this comment.
So you want to move 140 tests to expt.test?

no, just the new ones for ewm
