spark-fast-tests

Offers specialized methods like assertSmallDataFrameEquality and assertColumnEquality that run up to 70% faster than alternatives, as demonstrated in the benchmark table showing assertColumnEquality at 108 milliseconds.

Provides color-coded, readable diff outputs for data and schema mismatches, making failures easy to diagnose visually, as shown in the example images for assertSmallDataFrameEquality.

Works seamlessly with Scalatest, uTest, and MUnit, allowing integration into existing test suites without framework lock-in, as stated in the README's compatibility notes.

Avoids unnecessary dependencies like Hive, keeping the library lean and focused on core testing utilities, which simplifies dependency management and reduces bloat.
