Build Status

Features:

• consistent tests across multiple applications
• group assignment adjustments without code deploys
• rule-based group assignment: e.g. US users experience 50% A, 50% B and non-US users are 25% A, 25% B, 25% C, 25% D
• human-readable test format
• forcing of test groups for internal testing
• java code generation for A/B tests groups

Building

Need to use Java 11 SDK for using gradle:

List installed java JVMs on MacOS:

$ /usr/libexec/java_home -V

Example output:

Set JVM version in MacOS:

$ export JAVA_HOME=`/usr/libexec/java_home -v 11.0.18`

How to Build:

$ ./gradlew build

Local Install

Run the following gradle command and note the local version from the output:

$ ./gradlew clean check publish --refresh-dependencies 

Example output:

Calculating version to use for publish ...
Now using version: 0.local.20230711170543

> Task :proctor-common:compileJava

Example above would create local installation of proctor with version equal to 0.local.20230711170543
