Gate a release with test evidence

Ship it safely · Advanced · 18 min · Runs in your Salesforce Developer org · Apex Path

Scenario. A deployment pipeline must refuse ambiguous results instead of treating missing evidence as success.

Choose a safe Salesforce test level and block promotion without clean results and a rollback reference.

What you will learn

A release gate fails closed: missing evidence counts as a failure.

Deploys pick a test level: RunSpecifiedTests runs just the classes you name; RunLocalTests runs every local test (no managed packages).

String.isNotBlank(value) is true only when value is not null, empty, or whitespace.

Gotcha. null > 0 is false, not an error, so if (failures > 0) return false; lets null through. Check null first.

The task

Complete the release gate so it picks a test level and only allows promotion when the evidence is complete and clean.

Examples:

• named tests present → RunSpecifiedTests
• no usable test names → RunLocalTests
• 0 errors, 0 failures and rollback release-42 → promotion allowed; a null count → blocked

Requirements:

1. Return RunSpecifiedTests when at least one non-blank test name is supplied.
2. Return RunLocalTests when the set is null, empty, or holds only blank or null names.
3. Block promotion when either count is null or above zero. Remember null > 0 is false.
4. Block promotion when the rollback reference is blank.
5. Allow promotion only when both counts are zero and a rollback reference exists.

Starter code

public class AS_1E1E7AE44C28_ReleaseGate {
    public static String chooseTestLevel(Set<String> testNames) {
        return 'NoTestRun';
    }

    public static Boolean canPromote(
        Integer componentErrors,
        Integer testFailures,
        String rollbackReference
    ) {
        return true;
    }
}

When it passes

The temporary class chooses a test level from real inputs and allows promotion only with clean counts plus a rollback reference.
