Supply Chain Security
Software Composition Analysis (SCA) is now table stakes for secure development. But the tooling landscape is fragmented: there are commercial platforms, open source scanners, and everything in between. Choosing the wrong tool means either missing real vulnerabilities or drowning in false positives. This guide compares the four most widely-deployed
Docker
Docker HEALTHCHECK defines a command Docker runs periodically to determine container health. This guide covers writing HEALTHCHECK instructions, using health status in Compose depends_on conditions, testing health checks in CI, and debugging containers stuck in "starting" or "unhealthy" states. A running container is not necessarily
Docker Compose
Docker Compose creates complete multi-service environments for integration testing: your app, database, cache, and message queue all in one network. This guide covers writing test Compose files, running tests against them in CI, managing service startup order, and cleaning up after tests. Integration tests that run against real infrastructure—
Security Testing
Software Composition Analysis (SCA) identifies vulnerable open-source dependencies in your project. Snyk, Dependabot, and OWASP Dependency-Check are the three most widely used tools — each with different vulnerability databases, false positive rates, auto-fix capabilities, and pricing models. This guide compares them head-to-head. Why SCA Matters Modern
Django
Django ships with a robust testing framework built on Python's unittest. Knowing which tools to reach for — and when — separates tests that stay green for years from tests that rot the moment a colleague touches the model layer. This guide walks through the most important Django TestCase patterns
Test Strategy
Session-based test management gives structure to exploratory testing without scripting it. But most SBTM guides stop at the basics — charters, timeboxes, debrief. What they skip is the operational layer: how do you run SBTM with five testers across three feature areas? How do you measure coverage? How do you
Test Automation
Django ships with a solid test framework built on Python's unittest.TestCase. pytest-django adds pytest's ergonomics on top — fixtures, parametrize, concise assertions — without replacing Django's test infrastructure. Choosing between them shapes how your test suite reads and scales. Setup pip install pytest pytest-
Django
Unit tests verify logic. Integration tests verify that components wire together. But only browser tests prove that a user can actually complete a workflow. Django's StaticLiveServerTestCase combined with Selenium gives you a real browser that exercises your JavaScript, CSS, and server code together. When to Use Browser Tests
Testing
Software supply chain attacks have surged in recent years. SolarWinds, Log4Shell, and the XZ Utils backdoor all shared a common thread: attackers compromised components that developers trusted implicitly. A Software Bill of Materials (SBOM) is the foundational tool that lets you know exactly what is inside your software—and whether
Test Automation
Django REST Framework (DRF) provides APIClient and APITestCase — a layer above Django's test client with JSON handling and authentication helpers. Combined with pytest-django, you get a fast, ergonomic API testing workflow. Setup pip install djangorestframework pytest pytest-django Copy # settings/test.py INSTALLED_APPS = [ ... 'rest_framework&
Supply Chain Security
Generating an SBOM (Software Bill of Materials) is the easy part. The hard part is doing something useful with it — automatically enforcing policies that prevent vulnerable, unlicensed, or untrusted components from making it into your production builds. This guide covers the full SBOM lifecycle: generation, validation, policy enforcement, and continuous
Django
Django ships with unittest-based test tooling out of the box. pytest-django brings the full pytest ecosystem — fixtures, parametrize, plugins, and a cleaner API — to Django projects without rewriting your existing tests. This guide shows you how to set it up, what you gain, and when to reach for
