Description
3 flaky tests are found using Nondex when running commands
mvn edu.illinois:nondex-maven-plugin:1.1.2:nondexThe reasons for test flakiness are that Java Hashmap API do not preserve the order of the key-value pairs, and that Java Set API does not preserve the order of elements. Comparing maps or sets with strings can fail when, for example, the Java version upgrades in the future, or when the code is run in different environments.
Flaky Tests and Fixes
Using TreeSet instead of Set, and using LinkedHashMap instead of HashMap to ensure deterministic behavior in tests.
