Summary of changes

Migrates (what I think are) the remaining integration tests to use CombinatorialOrPairwiseData with the goal of speeding up PR CI runs with the hope of not missing regressions

Reason for change

As we have many tests our CI takes time running them, this aims to reduce some pressure as if a PR meets the criteria for running in Pairwise mode we will swap from combinatorial to pairwise for all of these integrations tests.

This will hopefully reduce times for runs that likely won't modify / impact these tests.

Implementation details

One commit per file with the following pattern(s):

  • Drop GetEnabledConfig() and the matching [MemberData(...)]
    • Replace with [CombinatorialOrPairwiseData]
  • Add Attributes : [PackageVersionData(nameof(PackageVersions.X))] and [MetadataSchemaVersionData]

Note that some tests needed a few more changes.

Test coverage

Less!

Same though on non-PR runs or on PR runs that end up on the thorough testing.

Other details

I have a planned follow up to reduce the V1 Schema tests that are run in general (the V0/V1 split causes most tests to be doubled for no real benefit as the move to the V1 schema has largely been replaced)

Benchmarks

Benchmark execution time: 2026-05-14 14:17:47

Comparing candidate commit 17e53b9 in PR branch steven/combinatorial-and-pairwise-migration-phase-1 with baseline commit 9c344fa in branch master.

Some scenarios are present only in baseline or only in candidate runs. If you didn't create or remove some scenarios in your branch, this maybe a sign of crashed benchmarks 💥💥💥
Check Gitlab CI job log to find if any benchmark has crashed.

Found 4 performance improvements and 3 performance regressions! Performance is the same for 49 metrics, 16 unstable metrics, 90 known flaky benchmarks, 36 flaky benchmarks without significant changes.

Explanation

This is an A/B test comparing a candidate commit's performance against that of a baseline commit. Performance changes are noted in the tables below as:

  • 🟩 = significantly better candidate vs. baseline
  • 🟥 = significantly worse candidate vs. baseline

We compute a confidence interval (CI) over the relative difference of means between metrics from the candidate and baseline commits, considering the baseline as the reference.

If the CI is entirely outside the configured SIGNIFICANT_IMPACT_THRESHOLD (or the deprecated UNCONFIDENCE_THRESHOLD), the change is considered significant.

Feel free to reach out to #apm-benchmarking-platform on Slack if you have any questions.

More details about the CI and significant changes

You can imagine this CI as a range of values that is likely to contain the true difference of means between the candidate and baseline commits.

CIs of the difference of means are often centered around 0%, because often changes are not that big:

---------------------------------(------|---^--------)-------------------------------->
                              -0.6%    0%  0.3%     +1.2%
                                 |          |        |
         lower bound of the CI --'          |        |
sample mean (center of the CI) -------------'        |
         upper bound of the CI ----------------------'

As described above, a change is considered significant if the CI is entirely outside the configured SIGNIFICANT_IMPACT_THRESHOLD (or the deprecated UNCONFIDENCE_THRESHOLD).

For instance, for an execution time metric, this confidence interval indicates a significantly worse performance:

----------------------------------------|---------|---(---------^---------)---------->
                                       0%        1%  1.3%      2.2%      3.1%
                                                  |   |         |         |
       significant impact threshold --------------'   |         |         |
                      lower bound of CI --------------'         |         |
       sample mean (center of the CI) --------------------------'         |
                      upper bound of CI ----------------------------------'

Comparison explanation

Execution-time benchmarks measure the whole time it takes to execute a program, and are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are highlighted in **red**. The following thresholds were used for comparing the execution times:

  • Welch test with statistical test for significance of 5%
  • Only results indicating a difference greater than 5% and 5 ms are considered.

Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard.

Graphs show the p99 interval based on the mean and StdDev of the test run, as well as the mean value of the run (shown as a diamond below the graph).
