How to Track and Manage Flaky Tests with TestRail

Flaky tests are one of the most annoying challenges in software testing. One day they pass without issues, and the next, they fail for no clear reason. This inconsistency not only wastes time but also weakens trust in your test suite—especially in fast-moving CI/CD environments.

So, how do you stay in control? A test management tool like TestRail can help you organize, monitor, and analyze test behavior over time. With features like result history, custom fields, reporting, and CLI automation, teams can identify unstable tests early and prevent them from slipping through unnoticed.

Let’s break down how it works.

Spot Flaky Tests Using Result History

The first step is understanding patterns—and that’s where TestRail’s result history becomes valuable. It stores detailed records of every test execution, making it easier to detect inconsistencies.

Example:
Imagine a login test that randomly fails even when nothing has changed in the code or environment. This could be due to issues like slow APIs, temporary server downtime, or network instability.

With TestRail, you can review past runs, identify when failures occurred, and correlate them with builds or system changes. This visibility helps pinpoint whether a test is genuinely broken or just unreliable.

Pro tip:
Encourage your team to add comments, logs, or screenshots directly to test results. This shared context makes debugging faster and more collaborative.

Flag Unstable Tests with Custom Fields

TestRail also allows you to create custom fields to highlight flaky tests, ensuring they don’t get ignored.

How to use it:

• Add a checkbox field like “Flaky Test” to mark unstable cases
• Use dropdowns to capture possible causes such as:
  • External dependency issues
  • Timing problems
  • Environment instability
• Filter and prioritize these tests during planning or review sessions

Example:
If a test repeatedly fails while connecting to an external service, tagging it as “flaky” immediately alerts the team. Over time, this builds a clear list of unstable tests that need attention.

Automate Test Logging with TRCLI

Managing flaky tests manually doesn’t scale well—especially in automated environments. That’s where TestRail’s CLI tool (TRCLI) comes in.

It allows you to automatically push test results from your CI/CD pipeline into TestRail, ensuring nothing is missed.

Key benefits:

• Automatically capture results from tools like Jenkins, GitLab CI, or GitHub Actions
• Analyze trends across multiple test runs using built-in reports
• Attach logs, screenshots, or comments for better debugging context

Example:
If your team uses Selenium, TRCLI can upload results after every run. Over time, you might notice a test failing only on a specific browser or dataset—giving you a clear direction for fixing the issue.

A Practical Workflow to Handle Flaky Tests

To truly stay on top of flaky tests, it helps to follow a structured approach:

1. Identify issues – Use result history and flag unstable tests
2. Prioritize fixes – Focus on tests with high impact or frequent failures
3. Collaborate – Share logs, notes, and findings within the team
4. Analyze root causes – Look for patterns like timing delays or environment issues
5. Apply fixes – Update test scripts or stabilize dependencies
6. Monitor continuously – Ensure resolved tests remain stable over time

This process not only reduces flakiness but also strengthens your overall QA strategy.

Why TestRail Makes a Difference

Flaky tests don’t have to slow your team down. With TestRail, you can:

• Detect patterns early using detailed execution history
• Stay organized by tagging and tracking unstable tests
• Automate workflows with TRCLI for accurate, real-time reporting

By combining these capabilities, you turn flaky tests from a recurring problem into a manageable part of your testing process—improving both reliability and team confidence.
