Quality as a Product: Treating QE Like Engineering
Most teams treat test results like a checkbox: green is good, red is bad, ship or block. The interesting signal lives in everything that happens between those two states — runtime variance, retry counts, the same five tests showing up in every postmortem. That signal is where engineering decisions actually get made.
In the world of continuous delivery and agile frameworks, quality engineering (QE) should be viewed not just as a gatekeeper, but as a product itself. This shift in perspective means adopting engineering practices that treat quality data points as part of a product lifecycle. The challenge lies in implementing systems that effectively harness this data to drive meaningful engineering outcomes.
By the end of this article, you'll understand how to treat QE like a product by integrating observability, pattern recognition, and advanced analytics into your workflows. This approach will help you transform raw test data into actionable engineering insights.
This approach becomes critical as modern architectures become more complex and teams scale. With tools like OpenTelemetry, Grafana, and Loki, we can now collect and visualize test results in ways that were previously inaccessible, making it an opportune moment to redefine our approach to quality engineering.
What This Actually Is
Treating quality engineering as a product involves treating your test infrastructure and outputs with the same respect you afford your software products. This means versioning your test suites, monitoring their performance over time, and iterating on them based on data-driven insights.
In a modern test architecture, this approach sits atop a foundation of CI/CD pipelines, test automation frameworks, and observability tools. By using platforms like Jenkins or GitHub Actions to automate test runs, and tools like Allure or ReportPortal for result aggregation, engineering teams can gain a comprehensive view of their application's health.
Quality as a product also means leveraging advanced analytics and AI-driven insights to detect patterns and anomalies in test results. This can involve using SQL queries on databases like ClickHouse or BigQuery to pull insights directly from your test result data, or employing Python scripts to analyze runtime variances.
How To Implement It
Implementing quality as a product starts by integrating observability into your test pipelines. Using OpenTelemetry, you can instrument your test runs to emit trace data, which can be visualized through Grafana for real-time insights. Below is an example of an OpenTelemetry configuration:
exporter:
otlp:
endpoint: "http://localhost:4317"
headers:
authorization: "Bearer "
service:
pipelines:
traces:
receivers: [otlp]
processors: [batch]
exporters: [otlp]
Once you have trace data, integrate it with a monitoring stack like Grafana and Loki to correlate logs and metrics with test outcomes. A sample Grafana panel JSON configuration could look like this:
{
"type": "gauge",
"title": "Test Execution Time",
"targets": [
{
"expr": "sum by(test_name)(rate(test_duration_seconds{job='ci'}[5m]))",
"format": "time_series"
}
]
}
For data-driven insights, use SQL to query your test results database. Here’s a PostgreSQL snippet to identify flaky tests:
SELECT test_name, COUNT(*) as failures
FROM test_results
WHERE status = 'failed'
GROUP BY test_name
HAVING COUNT(*) > 3
ORDER BY failures DESC;
By automating these analyses, you can reduce triage time from hours to minutes. A team at a Fortune 500 company reported cutting triage time from 22 minutes per failure to under 4 once their dashboards were wired to Loki and Grafana.
Common Pitfalls
One common pitfall is over-reliance on pass/fail metrics without context. Engineers often assume that a green build is sufficient for release, ignoring trends like increased execution time or high retry counts. This oversight is usually due to organizational pressure to ship quickly.
Another mistake is neglecting to version control test suites. As tests evolve, changes can introduce flakiness or false positives. Without versioning, tracking these regressions becomes challenging, leading to longer debugging cycles. Teams should use systems like Git for test scripts just as they do for application code.
Lastly, underestimating the need for dedicated observability into test results can lead to missed signals. Many teams fail to implement comprehensive monitoring solutions, relying instead on basic logs. Avoid this by integrating tools like Prometheus and Loki to gain full visibility into your testing ecosystem.
What Most Teams Get Wrong
A prevailing myth is that pass/fail is the ultimate signal of test quality. However, this binary view misses the nuances of test reliability and performance trends. The truth is that metrics like test runtime variance and retry count provide deeper insights into system behavior.
Another outdated practice is equating high test coverage with quality. While coverage is a useful metric, it doesn’t account for test effectiveness or redundancy. Focus instead on the impact of tests and the critical paths they cover.
Lastly, some teams believe flakiness is unfixable. This myth persists due to a lack of systematic triage and analysis. By employing data analytics and pattern recognition, flakiness can be minimized significantly, leading to more robust test suites.
Treating quality engineering as a product can transform your approach to testing, turning it into a source of actionable insights. When implemented correctly, this method provides a clearer path to understanding and improving your software's quality. As a next step, consider measuring the mean-time-to-first-signal on production incidents to further enhance your incident response strategies.
