How Bugs Escape

A loot at some ways Bugs escape QA

There are many reasons why bugs are missed by QA and eventually make it to Production. Here are some of the reasons that I have encountered over the years in various QA roles.

How Bugs Escape

Complexity

Sometimes bugs occur because the bug occurs during a complex situation. These are hard for QA to detect or identify.

For example: If you have 99 items in your cart and your language is French, the shopping cart page crashes.

Realistically these aren't going to be found by QA. With a little help from Devs, QA can formulate test strategies based on code changes. Such as learning more about a 3rd Party library or support for Unicode.

Time Constraint

QA Tasing time is finite. There's always too little time to test every possible situation.

This is why test strategies are so important. During off time, the QA team should get together and audit regression testing. The team should focus on what risk areas should QA be a focus on.

This is why developers' testing steps are important. QA should get a "heads up" on what to test.

Stale Test Case Repository

Bugs may escape QA because the manual test case repository tests might be state. How often are you looking at manual regression tickets? Are they update with the latest design changes? Are QA Testers actually following through the steps?

At previous companies that I have worked with, we review the manual regression steps with key stakeholders on a regular base. How often? Usually when there's a big design or code change. It's a good way to get some input in how QA is testing their product.

Don't take manual testing for granted. Make sure to review manual test cases on a regular base - especially if there's a lot of bugs making it in production.

A good QA Manager once told me, "that if an automation test case passes several releases, it should be audited. The test may not be challenging the code enough to be useful as part of regression."
