Effective testing process

Requirements validation

We conduct business requirement analysis based on the Guide to the Business Analysis Body of Knowledge®, which results in a specification and wireframes. Our QA specialists validate the requirements before development begins.

Test design & planning

All QA and testing activities are documented in the test strategy document that lists test environments, types of testing, and criteria for the start and end of testing. We store all information about tests in TestRail.

Test environment setup

The test environment includes test devices, OS versions, and apps that are involved in the testing process and have to be installed on devices. During this stage, our QA specialists ensure that the testing environment is ready.

Test execution

As soon as a chunk of functionality is implemented, we begin testing new features to verify that they work properly. We run functionality testing, regression testing, smoke testing, and a number of non-functional tests according to the test plan and checklist.

Automated testing

For projects that take more than six months to develop, we automate smoke testing, regression testing, and performance testing. We choose the most cost-effective test automation tools and processes.

Test reporting

We use Jira and TestRail to make our testing process visible. After each sprint, we present builds to our clients along with release notes showing our progress. We’re open with our clients about our development challenges.

Regular TestRail reports show the number of test runs and their results: passed, blocked, retest, failed, not ready, skipped, or fix in progress.

Crash statistic

With Crashlytics, we get crash reports that provide us with deep insights into the number of crashes and the issues that caused the app to crash.

Top-level metrics

We use Fabric to track metrics on users, sessions, and crash-free users, or the percentage of daily active users that had a crash-free experience on a given day.
