A simple, convenient testing library for Scala with uniform syntax, smart asserts, and support for Scala.js/Scala-Native.
uTest is a simple and convenient testing library for Scala that provides a uniform syntax for defining and running tests. It solves the problem of overly complex testing frameworks by offering essential features like smart asserts, test isolation, and multi-platform support in a minimal, easy-to-understand package.
Scala developers looking for a straightforward, no-fuss testing framework that works across JVM, Scala.js, and Scala-Native, especially those frustrated by the complexity of alternatives like Scalatest or Specs2.
Developers choose uTest for its simplicity, consistent syntax, and helpful debugging output from smart asserts, allowing them to write and maintain tests of any size without getting lost in framework complexity.

Provides a single, consistent way to define and run tests using `test("name"){...}` blocks, reducing the learning curve compared to multiple DSLs in other frameworks.
Macro-powered assertions automatically print variable names, types, and values on failure, eliminating the need for manual debug statements.
Supports `assertGoldenLiteral` and `assertGoldenFile` to auto-update test expectations with an environment variable, simplifying test maintenance.
Works seamlessly on Scala-JVM, Scala.js, and Scala-Native, and integrates with build tools like SBT, Mill, and Gradle.
Lacks BDD-style matchers and fluent syntaxes found in libraries like Scalatest, which might be preferred for readability in some teams.
Golden testing features are only available on Scala-JVM, not supported on Scala.js or Scala-Native, limiting cross-platform usage.
Tests must be statically defined at compile time and cannot be nested in loops, requiring workarounds like helper functions for dynamic test generation.
µTest is an open-source alternative to the following products:
