Connection Pool Exhaustion During Karate Labs Test Execution When running database integration tests through Karate Labs cloud platform, intermittent connection pool exhaustion can occur during parallel test execution. This symptom typically manifests as test failures with timeout or 'connection pool exhausted' errors that do not consistently reproduce in lo
Goal We want to validate client‑side logic against a Karate mock server without using production credentials, while also emulating realistic network delays and error conditions. Constraints The mock server does not automatically inject latency or TCP failures; it only returns predefined responses. When tests run in parallel, global variables modified by the
Configuration leakage in HTML reports Karate merges karate-config.js and environment-specific variants at startup, then serializes the full configuration object into the default HTML and JUnit reports. The 1.x release introduced an undocumented karate.configure('report', { showConfig: false }) option intended to suppress this output, but the flag does not co
In Karate 1.x, the match keyword provides a # wildcard that tolerates unspecified fields in API responses, allowing limited schema change tolerance without test failure. However, when a new required field is introduced, the same match block fails, indicating the need for manual updates. The call and callonce mechanisms reduce duplication by reusing request a
In Karate, the karate-config.js file typically uses the karate.env variable to assign a baseUrl based on the target environment (e.g., dev, staging, or prod). While this configuration works reliably during local execution where the environment is explicitly passed, it can lead to failures in production or CI/CD pipelines if the variable is not correctly reso
Goal: Ensure that Karate DSL selects the correct environment block from karate-config.js consistently across local development and production CI pipelines. Constraint: Karate reads only the JVM system property karate.env to determine which environment to load; it does not consult the OS environment variable KARATE_ENV. When CI provides only KARATE_ENV, the f
Goal Validate JSON API responses in Karate DSL while tolerating server-added dynamic fields such as timestamps and generated IDs. The project uses Karate’s built-in JSON matchers. `match equals` requires an exact body match and fails when the response includes any undeclared key. `match contains` asserts only the expected subset and ignores extra fields, but
When Karate’s built‑in response cache is enabled with karate.configure('cache', true) , identical requests return the stored response without contacting the server. The goal is to use this cache to speed up test execution while guaranteeing that each scenario sees the current state of the backend, even when the service modifies data during a suite run. Becau
