Testing
Kaspresso is an Android UI test framework built on top of Espresso and UIAutomator. It solves the two biggest problems with raw Espresso: flaky tests and unreadable test code. With Kaspresso, you get a clean Kotlin DSL (via Kakao), automatic waiting and retry logic, and first-class Allure report integration. If
Testing
Jetpack Compose has its own testing APIs that don't use Espresso's view matchers. Instead, Compose tests work against the semantics tree — an accessibility-oriented representation of your UI that's separate from the rendering layer. This makes Compose tests faster and less brittle than Espresso tests
Testing
Robolectric runs Android tests on the JVM — no emulator, no device, no waiting for adb to connect. It implements Android's framework classes as JVM-compatible stubs, so your Activities, Fragments, ViewModels, and Repositories run in a regular JUnit test process. A Robolectric test suite that takes 30 seconds to
Security Testing
The NIST Cybersecurity Framework (CSF) provides a flexible structure for managing cybersecurity risk. Unlike FIPS 140 or SOX, the CSF is not prescriptive — it describes outcomes, not specific controls. This makes it adaptable but also harder to test against. This guide maps CSF functions and categories to concrete automated tests.
Security Testing
FIPS 140-2 (and its successor FIPS 140-3) defines security requirements for cryptographic modules used in federal systems. If your application handles sensitive government data or pursues FedRAMP authorization, you need to use FIPS-validated cryptographic modules. Testing verifies your code actually uses them. What FIPS 140-2/3 Requires FIPS 140-2 defines
Security Testing
ISO 27001 is the international standard for information security management systems (ISMS). Certification requires demonstrating that security controls are implemented, tested, and continuously monitored. For developers, this translates to a specific set of testing responsibilities — most of which can be automated. What ISO 27001 Requires Developers to Test ISO 27001
Testing
App performance isn't tested — it's measured. Android's Macrobenchmark library gives you a framework for measuring startup time, frame rendering, and custom interactions on real devices. Baseline Profiles use those measurements to pre-compile critical code paths, and Perfetto lets you trace exactly what's
Security Testing
FedRAMP (Federal Risk and Authorization Management Program) is the U.S. federal government's standard for cloud service security. If your product serves federal agencies, FedRAMP authorization is required. The security testing requirements are among the most rigorous in any compliance framework — and a significant portion can be automated.
Visual Testing
Reg-Suit is a visual regression testing framework built around a plugin architecture. Unlike tools that are opinionated about screenshot capture, Reg-Suit focuses on the comparison and reporting layer — you bring your own screenshots, and Reg-Suit handles storage, comparison, and CI status reporting. Architecture Reg-Suit separates three concerns: 1. Screenshot capture
Visual Testing
Loki is a visual regression testing tool purpose-built for Storybook. It runs locally and in CI, captures screenshots of every story, compares them against stored references, and shows diffs when components change. Unlike cloud-hosted alternatives, Loki stores reference images in your repository and runs entirely offline. Why Loki Loki fills
Visual Testing
Happo solves a specific problem: visual regression testing across multiple browsers simultaneously. While Chromium-only tools catch 80% of visual regressions, cross-browser differences — font rendering, flexbox quirks, Safari's date inputs — require testing against real browser engines. Happo runs your components in Chrome, Firefox, Safari, and Edge and compares screenshots
Visual Testing
Visual regression testing catches UI changes that unit tests miss. Lost Pixel is an open-source visual regression testing platform that compares screenshots of components or pages across commits, flags differences, and integrates with your existing CI pipeline. Unlike hosted-only tools, Lost Pixel can run entirely in your own infrastructure. What
