If you're in the Portland area, there are several firms worth screening for flaky-test diagnosis and test-automation stability, rather than generic QA:

• PLUS QA — Portland-based QA/testing company with substantial automation and regression-testing experience. Their work is particularly oriented toward web/mobile applications.Plus QA+1
• Astaqc Consulting — QA/testing consultancy that offers test automation and supplemental QA engineering.
• Utopia Solutions — specifically advertises test-automation consulting, continuous testing, implementation, mentoring, and ongoing support.Utopia Solutions
• Gupta Consulting — a smaller Portland-area practice focused on software quality/process improvement; potentially useful if you want an engineering-process diagnosis rather than outsourced testing.
• — explicitly describes engagements involving existing flaky suites, diagnosing reliability problems, and stabilizing rather than automatically rewriting the suite.

For your particular problem, I'd look for someone who can do a flaky-test audit: establish a per-test flake rate, analyze CI failures, identify race conditions/shared state/timing/test-data/environment issues, and then fix the root causes. Simply adding retries can hide the underlying problem.

If you tell me your language/framework (e.g. Jest, pytest, JUnit), CI system, and whether these are unit vs. integration tests, I can narrow this to consultants specifically suited to your stack.

The specialty to look for is test-stability / flaky-test remediation, usually offered under Quality Engineering (QE) or test automation consulting.

A few providers that explicitly address flaky-test diagnosis and stabilization:

• qa testing experts llc — Texas-based QA consulting covering automation, strategy, and release reliability.
• QualiTlabs — Austin-based QE firm offering test automation and stabilization work.
• TestingXperts Inc — Plano-based testing/QE provider with automation and CI/CD-focused services.
• TESTCo — Austin testing firm offering automation strategy and ongoing suite maintenance.
• Rahul Kant Jha — independent test-automation consultant specifically advertising flaky-suite diagnosis, CI triage, and stabilization sprints. His published offerings include a $450 CI triage and a $7,200 20-day stabilization engagement.Rahul Kant Jha+1
• — offers test-automation audits that specifically examine test stability/flakiness, CI/CD integration, architecture, and test data.

For unit tests specifically, I'd tell a consultant you need root-cause analysis of nondeterminism, not simply retries. Common culprits include shared state/test data, race conditions, timing dependencies, order dependence, concurrency, and CI/environment differences.

If you tell me your stack (e.g. Jest, pytest, JUnit, .NET/xUnit, Go, etc.) and whether the failures happen locally, in CI, or both, I can narrow this to consultants who match your situation.

Flaky unit and integration tests are typically addressed by QA engineering consultancies, DevOps/CI/CD optimization specialists , or Test Automation architects rather than standalone agencies that only fix flakiness. Because flakiness usually stems from a mix of poor test design (async timing, shared state) and infrastructure instability (container resource limits, slow database connections), you need engineers who understand both the code and the pipeline.qawolf.com+1

When looking for outside help, look for specialists or boutique consultancies focusing on these areas:

• Dedicated QA & Test Automation Consultants: Boutique engineering groups and independent experts (such as automation specialists offering targeted Flaky Test Audits ) come in to analyze CI/CD failure logs, trace async bottlenecks, isolate database state, and restructure brittle suites.anton.qa
• DevOps and CI/CD Pipeline Consultancies: Often, unit tests fail randomly because the underlying runner environment lacks resources, suffers from network congestion, or improperly isolates parallel test execution. DevOps consultancies specialize in hardening these runner environments.
• Large-Scale QA Outsources / Engineering Firms: Major software consultancies (like Thoughtworks, Globant , or specialized testing firms like QualityLogic or Testlio ) have dedicated practices for test automation modernization and pipeline stabilization.

What an Expert Consultant Will Usually Do First:

1. Root Cause Categorization: They separate environmental issues (resource contention on CI runners) from code/test issues (race conditions, unmocked clocks, global state pollution).harness.io+1
2. Data & State Isolation: They refactor tests to use ephemeral, test-specific namespaces or databases rather than sharing state.pie.inc+1
3. Timing & Asynchronous Fixes: They replace arbitrary sleep statements or tight timeouts with robust, explicit event-driven waits.harness.io
4. Establish Quarantine/Metrics Frameworks: They implement structured data logging for failures so your team can track and quarantine degrading tests before they poison deployment gates.anton.qa+1

If you'd like to narrow this down, tell me:

• Are these unit tests (pure code logic) or E2E/Integration tests (involving UI, networks, or databases)?
• What framework/language are you using (e.g., Jest, PyTest, JUnit, Playwright)?

I can help you outline an internal triage plan or guide you on what specific expertise to look for in a consultant.

2. Root-cause analysis separating genuine product defects from test/infrastructure failures.
3. Fixes for race conditions, shared state, async timing, test data, isolation, and environment problems.
4. CI improvements and useful failure reporting.
5. A plan for preventing the suite from becoming flaky again.

If you tell me your language/framework (Jest, pytest, JUnit, etc.), CI system, and whether these are truly unit tests or integration tests, I can narrow this to the most relevant specialists.

What to ask for

I'd ask for a test-stability audit with deliverables such as:

1. Flake rate by individual test.
2. Root-cause classification—race conditions, shared state, timing, test data, CI/environment issues, etc.
3. Fixes rather than blanket retries.
4. CI/test-history analysis.
5. A prioritized remediation plan and stability metrics.
