Quality assurance techniques for every challenge

manual-testing-pillar-icon-smoke-test

Smoke testing

A technique that involves taking short passes through elements of your product experience that we expect to work. Failed smoke tests may demonstrate build problems, and can lead to more extensive exploratory or scripted tests.

manual-testing-pillar-icon-exploratory-test

Exploratory testing

A powerful technique for testing new features when quick turnarounds are of the essence. Our testers learn about your product, risks, and previous failures to create new tests, driven by missions with clear objectives and often tied to critical pathways.

manual-testing-pillar-icon-scripted-test

Scripted testing

A technique used when testing must be consistent, and the product is relatively stable. Testers follow a step-by-step procedure and validate that each step of the process operates by design. Scripted testing is often used for regression testing.

Our team works to describe, reproduce, streamline, and make actionable all issues discovered. This technique ensures that issues that enter your engineering systems and backlog are highly relevant and addressable.
