Description

Backports PR #4085 ("Address flaky DEBUG assertions") to the release/7.0 branch.

Fixes flaky test failures in the 7.0.x test suite by refactoring DataTestUtility assertion helpers and fixing race conditions in DataStreamTest.cs.

Changes

DataTestUtility.cs — Assertion helper redesign

Replaced the three AssertThrowsWrapper overloads with four properly-typed, well-documented helpers:

Old Method New Method What Changed
AssertThrowsWrapper(...) AssertThrows(...) Removed unused params (innerExceptionMustBeNull, customExceptionVerifier)
AssertThrowsWrapper(...) AssertThrowsInner(...) Now actually validates the inner exception type via Assert.IsAssignableFrom
AssertThrowsWrapper(...) AssertThrowsInnerWithAlternate(...) Accepts two possible inner exception types for race conditions

DataStreamTest.cs — Race condition fixes

  • Extracted WaitIgnoringFlakyException(Task) helper to replace 6 duplicated try/catch blocks
  • Fixed race-prone assertion sites using AssertThrowsInnerWithAlternate

22 other test files — Assertion renames

All call sites updated from AssertThrowsWrapper to the new names.

Testing

  • Cherry-pick of a11341f5 applied cleanly to release/7.0 with no conflicts
  • PR diff shows exactly the 24 files changed in the original PR

Checklist

  • Tests added or updated
  • Public API changes documented (N/A — test-only changes)
  • Verified against customer repro (if applicable)
  • Ensure no breaking changes introduced

* Couple more comments from copilot

* downgrade back to 7.0.0 :)

* Test | Fix Transient Fault handling flaky tests

* Attempt to fix

* Fix the MultiPartIdentifier tests getting skipped

* Fix serialization issue of SqlTypeWorkaroundsTests

* Fix one more cases of possible error scenarios
* Task 40503: Create stress test pipeline

- Added initial placeholder pipeline entry point file.
- Wired up the new top-level stress test pipeline to the existing stages/jobs.
- Using human friendly triggering pipeline names.
- Removed PR pipeline as upstream trigger.
- When triggered manually, we must choose one of the upstream pipelines to use for artifact download.
- Temporarily added PR-SqlClient-Package to help with PR-based testing.
- Sorted template parameters alphabetically.
- Added debugging for artifact details.

* Changed the pipeline to expect project-references to SqlClient projects.

* Moved stress test pipeline files into a stress/ directory.

* Fixed expansion errors.

* Addressed Copilot feedback.

* Addressed my own comments.
* Drop compound-* from onebranch step files for my own sanity

* Consolidate compound-publish-symbols and publish-symbols-step into publish-symbols-step.

* Rename code-analyze-step to roslyn-analyzers-csproj-step (for later changes)

* Add mds-specific job/steps

* Swap in build-signed-mds-package-job.yml for build-signed-sqlclient-package-job.yml

* Remove dead job/steps

* Fix folder path for DLL signing steps.

* Addressing comments, round 1

* Addressing comments, round 2

Not sure how the PackBuild target got lost, but I brought it back

* Add the new parameters to the csproj build job

* Use variables artifact names in release stage

* Two more quick fixes as per comments

* ESRP searches recursively?

* Fine, I give up, I will put the package output in PACK_OUTPUT.

* Reinstate job-level apiscan parameter assignment

* Wire isOfficial to MDS build job after rebase

* Rework versioning logic and move package version calculation (outside of pipelines) entirely to MdsVersions.props

* Add build number to PackMds target call in official pipeline

* Remove assembly "file" versions as it is not necessary.

* CI pipelines to automatic versioning system.

* Rework the package version for CI to match the package version for OneBranch. This band-aid avoids completely messing with the CI properties.

* Assembly version = major.0.0.0
File version = major.minor.patch.build
Package version = major.minor.patch[-suffixbuildnumber]

* Comment that Malcolm is holding the build up for.

* Can I please be done with this PR now?
