Missing code coverage for Array Results using [] notation

[EmmaMunley]

Expected Behavior

I was looking for an unit test of using array indexing to reference results in a pipelineTask.

It was confusing to me since the yaml example file with matrix results is different than the test in pipelinerun.go with the syntax:

https://github.com/XinruZhang/pipeline/blob/8b80e76f7ba28aa0281a7fa9d038f73dddad9b77/examples/v1beta1/pipelineruns/alpha/pipelinerun-with-matrix-and-results.yaml#L17

pipeline/pkg/reconciler/pipelinerun/pipelinerun_test.go

Line 8716 in a0b5cc5

func TestReconciler_PipelineTaskMatrixWithResults(t *testing.T) {

A

            value:
              - $(tasks.pt-with-result.results.platform-1)
              - $(tasks.pt-with-result.results.platform-2)
              - $(tasks.pt-with-result.results.platform-3)

B

            value:
              - $(tasks.pt-with-result.results.platform[0])
              - $(tasks.pt-with-result.results.platform[1])
              - $(tasks.pt-with-result.results.platform[2])

Actual Behavior
