mre-missing-output-for-aggregated-only-coverage

Minimal reproducible example to demonstrate a bug where sf apex run test --code-coverage --wait 10 does not output the Apex Code Coverage by Class when "Store Only Aggregated Code Coverage" is enabled in the Test Execution settings (apexSettings > enableAggregateCodeCoverageOnly > true).

Important

A green status badge means the issue was successfully reproduced.

A red status badge means the issue was fixed or the pipeline failed for another reason.

Expected

The output after === Apex Code Coverage by Class should look like:

=== Apex Code Coverage by Class
CLASSES  PERCENT  UNCOVERED LINES
───────  ───────  ───────────────
Greeter  100%

Actual

The output after === Apex Code Coverage by Class is empty:

=== Apex Code Coverage by Class

Workaround

We can query and format the Apex Code Coverage by Class (with "Store Only Aggregated Code Coverage" enabled) using the Tooling API (SELECT ApexClassOrTrigger.Name, NumLinesCovered, NumLinesUncovered FROM ApexCodeCoverageAggregate).

Instructions

Note

"Store Only Aggregated Code Coverage" is enabled in config/project-scratch-def.json.

sf org create scratch -f config/project-scratch-def.json --alias mre-missing-output-for-aggregated-only-coverage --set-default
sf project deploy start
sf apex run test --test-level RunLocalTests --code-coverage --wait 10
