Healenium is a self-healing test automation tool that is open-source and designed to enhance the stability of Selenium-based tests by adapting to alterations in web elements. As UI modifications can often disrupt locators, leading to maintenance challenges, Healenium automatically identifies and substitutes a malfunctioning locator with the most suitable match for the intended element, thereby correcting the test during execution. In the event of a NoSuchElement error, it evaluates the current state of the webpage against the previously successful locator, generates potential corrective locators, selects the one with the highest compatibility, and proceeds with the test using this replacement. This automatic adjustment significantly curtails non-functional test failures, lessens the burden of maintaining automation code, and bolsters the reliability of end-to-end testing and Continuous Integration (CI) processes. Moreover, Healenium seamlessly integrates with various Selenium-based automation frameworks and offers support for parallel and remote test executions, IFrames, Actions, Selenide integration, and mobile testing through Appium, making it a versatile choice for developers. Its ability to enhance test resilience in dynamic environments sets it apart as an essential tool in the realm of test automation.

Every app, build pipeline and AI agent that calls Stripe, OpenAI or any other third-party API needs that API key. So copies of live keys pile up in .env files, CI settings, laptops and agent environments, and each copy is one more place a key can leak from: a poisoned package, a prompt-injected agent, a compromised build or a config file pushed by mistake. A stolen key keeps working until someone notices, then has to be replaced everywhere it was copied. KnoxCall keeps the real key in one place and adds it to each call on its way out. Your apps, pipelines and agents hold only a KnoxCall token. If a token leaks, one click revokes it everywhere, without rotating the provider key. Every call is logged with the name of the app or agent that made it. Because every call already passes through KnoxCall, it's also the natural place to put guardrails on AI agents. Each agent can be given its own spending limit, every prompt is checked before it reaches the model, and the personal data KnoxCall detects is swapped out before the model sees it, then put back in the reply. Security teams stay in control of the foundations. CI jobs can authenticate with workload identity instead of a stored secret, and on the Enterprise plan you can lock your keys with a master key held in your own cloud account and manage access through your existing single sign-on and SCIM provisioning. KnoxCall fits the stack you already use, with SDKs for Node, Python, Go, PHP, Ruby, React and the browser. Start on the free plan with no card required, or move to a paid plan from $19 a month.
