loadtest4j-example-scala

A working example of loadtest4j in Scala and SBT.

Usage

Normal

sbt test                            # Run unit tests

sbt it:test                         # Run integration tests

sbt lt:test                         # Run load tests (in the default environment)

sbt "profile staging" lt:test       # Run load tests (in the 'staging' environment)

sbt "profile production" lt:test    # Run load tests (in the 'production' environment)

SBT Shell

sbt shell
>
> test                # Run unit tests
>
> it:test             # Run integration tests
>
> lt:test             # Run load tests (in the default environment)
>
> profile staging     # Activate 'staging' environment
> lt:test             # Run load tests (in the 'staging' environment)
>
> profile production  # Activate 'production' environment
> lt:test             # Run load tests (in the 'production' environment)
>
> reload              # Revert to the default environment
>
> lt:test             # Run load tests (in the default environment)

Caveats

• SBT does not currently support resource filtering. This means that Maven-style foo = ${bar} property interpolation is not available. As a consequence, loadtest4j config cannot be specified in loadtest4j.properties, instead it must be set as JVM system properties in build.sbt.
• IntelliJ IDEA sometimes forgets that src/lt/scala is a test source directory. If this occurs you can fix it by re-marking src/lt/scala as a test source directory.
• You must run load tests from the SBT shell or command line. This is due to two missing features in IntelliJ IDEA:
  • IntelliJ IDEA does not currently support SBT Configurations (to pick up loadtest4j custom environments).
  • IntelliJ IDEA does not currently read testOptions from build.sbt (to pick up any loadtest4j config that is defined as a JVM property in build.sbt).
