HubSpot's v3 API uses standard REST/JSON, making it accessible to any HTTP testing tool. This guide covers testing contacts, deals, workflows, webhooks, and custom objects — with patterns for keeping tests isolated and fast. HubSpot API Overview HubSpot's v3 API is well-structured and consistent: * Base URL:

TruLens is an open-source observability and evaluation framework for LLM applications. Its core contribution is the RAG Triad — three metrics (groundedness, context relevance, answer relevance) that together diagnose where a RAG pipeline breaks. Traces are stored locally or remotely, and a built-in dashboard makes debugging fast. What TruLens Does TruLens

Testing data quality in Snowflake requires both SQL-based tests (dbt works natively with Snowflake) and Python-based data validation (Great Expectations connects via the Snowflake SQLAlchemy adapter). Run dbt tests for schema and transformation validation, Great Expectations checkpoints for statistical and pattern-based assertions, and scheduled CI pipelines to catch issues before

Dynamics 365 UI testing requires EasyRepro — Microsoft's open-source Selenium wrapper that understands D365's dynamic control IDs. This guide covers EasyRepro setup, Dataverse API testing, Power Automate flow testing, and integrating everything into CI. Why Dynamics 365 Testing Is Hard Testing Dynamics 365 with standard Selenium fails

LangSmith gives you production observability for LLM applications — full request traces, cost tracking, latency breakdowns, and human annotation queues. Combined with its evaluation layer, you can compare prompt versions, run automated evaluators, and catch regressions before they reach users. Why Tracing Matters for LLM Applications An LLM application isn'

Testing pandas code requires different patterns than testing application code. DataFrames are complex objects—you rarely want to assert on the entire DataFrame at once. Instead, assert on specific columns, row counts, data types, and statistical properties. Use pytest fixtures for reusable test data, pandas.testing for DataFrame comparisons, and

SAML SSO testing requires testing both SP-initiated and IdP-initiated flows, SAML assertion validation (signature, conditions, audience), and error handling for invalid assertions. Most teams only test the happy path through the browser UI. This guide covers automated testing of SAML assertion handling, IdP simulation for integration tests, and the security

ServiceNow's Automated Test Framework (ATF) is a built-in, no-license-required testing tool that supports UI tests, server-side script tests, and API tests. This guide covers ATF setup, test writing patterns, and CI/CD integration using the ServiceNow REST API. What Is ServiceNow ATF? The Automated Test Framework (ATF) is

Promptfoo is the standard tool for prompt regression testing and LLM red-teaming. Define test cases in YAML, run them against multiple models simultaneously, and catch prompt regressions before they reach production. The red-team mode automatically probes for jailbreaks, prompt injection, and safety failures. The Problem Promptfoo Solves Every time you

Session management testing covers four areas: cookie security attributes (HttpOnly, Secure, SameSite), CSRF protection, token refresh behavior, and session lifecycle (creation, invalidation, concurrent sessions). These aren't glamorous tests, but session vulnerabilities — session fixation, missing CSRF protection, cookies over HTTP — are consistently in the OWASP Top 10. This guide
Testing
Data pipeline orchestrators (Airflow, Prefect, Dagster) each have different testing models, but the principle is the same: unit-test your business logic in isolation, integration-test the orchestration layer with real or containerized dependencies. This guide covers testing patterns for all three orchestrators plus shared practices that apply to any pipeline. Key

Keycloak testing requires a dedicated test realm to isolate test users and configuration from production. The Keycloak REST Admin API handles test setup and teardown — creating users, resetting passwords, and managing roles programmatically. For E2E tests, token generation via the Direct Access Grant bypasses browser login. This guide covers Keycloak
