Fix Mutation Testing - Adding Environment Variables to Gradle Pitest Plugin

[valentinajemuovic]

Mutation testing used to work, but stopped working after the addition of environment variables

The error is:

` 4:46:45 PM PIT >> SEVERE : Tests failing without mutation: Description [testClass=com.optivem.kata.banking.BankingApplicationTests, name=[engine:junit-jupiter]/[class:com.optivem.kata.banking.BankingApplicationTests]/[method:contextLoads()]] Exception in thread "main" org.pitest.help.PitHelpError: 1 tests did not pass without mutation when calculating line coverage.

I was searching for "Gradle Pitest Plugin Environment Variables"

I tried to set the environment variables, based on this https://stackoverflow.com/questions/56159077/set-environment-variables-in-gradle-pitest-plugin

tasks.named('pitest') { environment('env:POSTGRES_URL', 'jdbc:postgresql://localhost:5432/banking_kata') environment('$POSTGRES_USER', 'postgres') environment('POSTGRES_PASSWORD', 'admin') }

But still doesn't work.

Plan to continue further search.
