Testsigma
Testsigma is an agentic test automation platform covering web, mobile, API and Salesforce. Named agents map every commit to the stories and specs behind it, generate test plans in plain English, run them across thousands of real browsers and devices, self-heal locators when the UI changes, and produce a coverage and confidence score at the release gate.
- Attacks maintenance, which is the real cost of test automation
- Healing events shown in run output rather than hidden
- Starting from the commit keeps coverage tied to what actually changed
- Salesforce treated as a first-class surface, which is genuinely hard
- A confidence score can launder an assumption into a metric
- Coverage of generated tests is coverage of what was specified
- Self-healing can silently re-target a test onto the wrong element
