FAQs
What are flaky tests and why are they problematic?
Flaky tests pass and fail inconsistently without any code changes, causing headaches for development teams. They create false alarms that erode trust in your test suite and slow down the entire development process. When engineers can't trust test results, they either waste time investigating non-issues or start ignoring failures altogether—both terrible outcomes. Flaky tests typically stem from timing issues, race conditions, or dependencies on external services. Left unchecked, they can significantly drag down productivity and release velocity as teams spend countless hours debugging phantom issues instead of shipping features.
How does Trunk Flaky Tests differ from testomat.io in handling flaky tests?
Trunk Flaky Tests focuses specifically on flaky test detection and management with dedicated quarantining capabilities, while testomat.io offers a broader test management platform with flaky test handling as one component. The main difference is in specialization and approach—Trunk automatically identifies test flakiness patterns using sophisticated Flaky Test Detection algorithms and then isolates problematic tests through Test Quarantining Techniques to prevent them from blocking your CI pipeline. Testomat.io, meanwhile, takes a more generalized approach within their overall test management solution, offering detection but not the same level of automated quarantining and workflow integration that Trunk provides.
What solutions does testomat.io offer for handling flaky tests?
Testomat.io provides test analytics that help identify inconsistent test behavior and flakiness metrics to track problematic tests. Their platform can flag tests that sometimes pass and sometimes fail, giving you visibility into which tests need attention. They offer integration with existing CI/CD tools to collect test results and generate reports. However, testomat.io's approach is more focused on identification and reporting rather than automatic remediation. While they provide valuable insights, they don't offer the same level of automated quarantining that Trunk does with its Test Quarantining Techniques, which means developers still need to manually manage flaky tests once they're identified.
How does Trunk Flaky Tests integrate with existing CI/CD pipelines?
Trunk Flaky Tests is designed to work with virtually any CI/CD setup with minimal configuration changes. It integrates seamlessly with popular CI providers like GitHub Actions, CircleCI, Jenkins, and others through a lightweight agent that monitors test results. The Flaky Test Uploader sends test results to Trunk's platform for analysis without disrupting existing workflows. Trunk's deep GitHub integration provides instant feedback through GitHub Pull Request Comments, showing developers exactly which tests are flaky right where they're already working. Additionally, webhook integrations with Slack Integration and GitHub Issues Integration enable automated notifications and ticket creation for flaky tests.
How does testomat.io integrate with existing CI/CD pipelines?
Testomat.io connects to CI/CD pipelines through API integrations and test result collectors that feed data into their reporting platform. They support major CI tools and provide test status visibility through their dashboard. Their Jira integration allows for test results to be linked with project management workflows, though it doesn't have the same direct feedback loop in pull requests that Trunk offers. Testomat.io's approach focuses more on centralized test management rather than providing real-time feedback within the development workflow itself. While useful for overall test management, it creates an additional dashboard that developers need to check rather than bringing insights directly to their existing tools.
What analytics and reporting features does Trunk Flaky Tests offer?
Trunk Flaky Tests provides comprehensive analytics focused specifically on flakiness patterns and trends. The dashboard shows historical flakiness rates, identifies the most problematic tests, and tracks progress in reducing flakiness over time. Engineers can drill down into individual test failures to see patterns that might reveal underlying causes. The platform automatically correlates flaky tests with code changes and identifies potential triggers. Beyond raw data, Trunk provides actionable insights about the root causes of flakiness and recommendations for fixing them. Metrics like "time saved" help teams quantify the productivity benefits of addressing flaky tests, making it easier to justify the engineering effort required to fix them.
What analytics and reporting features does testomat.io offer for flaky tests?
Testomat.io's analytics platform provides broader test management metrics with flaky test identification as one component. Their "Ever-failing tests" metric helps identify consistently problematic tests, while their flakiness reports show test stability across different runs. The platform visualizes test result trends over time and can highlight anomalies in test behavior. Testomat.io offers good visualization of test execution data and can generate reports for stakeholders. However, their analytics cover the entire testing process rather than specializing in flaky test patterns specifically, which means they provide broader but sometimes less detailed insights about flakiness causes compared to Trunk's focused approach.
What specific methodologies does Trunk Flaky Tests use to identify flaky tests?
Trunk uses sophisticated statistical analysis and machine learning to identify flaky tests with high accuracy. The Flaky Test Detection system analyzes test execution patterns across multiple runs to distinguish between genuine failures and flaky behavior. It considers factors like historical test performance, run-time variations, and context-specific patterns. Trunk's detection algorithms look for subtle signs of flakiness even before a test shows obvious pass/fail inconsistency, allowing for proactive identification. The system continuously learns from new test data while maintaining data privacy, improving detection accuracy over time. Trunk can identify different categories of flakiness (timing-related, resource contention, external dependencies) and provide appropriate remediation suggestions for each type.
What specific methodologies does testomat.io use to identify flaky tests?
Testomat.io identifies flaky tests primarily through statistical analysis of test results over time, looking for inconsistency patterns in pass/fail rates. Their platform tracks "Ever-failing tests" metrics to highlight tests that fail intermittently. They analyze test runs across different environments to detect environment-specific flakiness. The system flags tests with variable execution times, which can indicate potential timing-related flakiness. While testomat.io provides good visibility into which tests are behaving inconsistently, their methodology focuses more on statistical detection rather than the deeper pattern analysis and categorization that Trunk offers. Their system requires more historical data to confirm flakiness compared to Trunk's more sensitive detection algorithms.
How does the pricing of Trunk Flaky Tests compare to testomat.io?
Trunk Flaky Tests offers a more flexible pricing model, including a free tier for open-source projects and small teams (up to 5 committers). For larger teams, Trunk uses a per-seat model that scales with your team size. Testomat.io typically uses a tier-based pricing structure based on the number of test runs and features needed. While both tools offer enterprise pricing for larger organizations, Trunk's free offering for open-source projects makes it more accessible for community projects. Testomat.io's pricing reflects its broader test management capabilities, while Trunk's focused pricing is specifically for flaky test management. For teams primarily concerned with flaky tests rather than comprehensive test management, Trunk often provides better value.
Which teams benefit most from using Trunk Flaky Tests versus testomat.io?
Teams with large, fast-moving codebases and high PR volumes benefit most from Trunk Flaky Tests, especially those experiencing significant productivity loss due to flaky tests. Engineering organizations focused on CI/CD efficiency and developer productivity finds Trunk's specialized approach particularly valuable. Teams heavily using GitHub and wanting direct integration in their workflow see more benefits from Trunk's GitHub Pull Request Comments feature.
