Test icons

The 19 test icons, described

Ablationablation

An ablation — take one part of a system out and see what breaks.

Assert failassert-fail

An X held between brackets — an assertion in the code that failed its check.

Assert passassert-pass

A check held between brackets — an assertion in the code that held true.

Canarycanary

A canary release — one instance running the new version so problems show up early.

Continuous integrationci

Continuous integration — every change built and tested automatically as soon as it lands.

Dataset splitdataset-split

A dataset split — most rows to learn from, some held back to be judged on.

Evaluationevaluation

Evaluation — measuring how good a model's output is with tests, scores and benchmarks.

Experimentexperiment

An experiment — a flask for trying something and seeing what happens.

Experiment armexperiment-arm

An experiment arm — the branch of users that gets the new thing.

Fault injectionfault-inject

Fault injection — break it yourself before the world does, a chaos test.

Flaky testflaky-test

A flaky test — one that passes and fails on the same code, unreliable and intermittent.

MCP inspectormcp-inspector

The MCP inspector — the tool you debug and test a server with.

MCP server testmcp-server-test

MCP server test — run the server against a pretend client before it goes live.

Mutant killmutant-kill

A crossed-out mutant — a mutation the test suite caught and killed.

Needle in a haystackneedle-haystack

One point hidden among many lines — the needle-in-a-haystack test of long-context recall.

Safety probeprobe-safety

A safety probe — a thin question lowered into the model to test what it knows.

Stubstub-tool

A stub — looks like the tool but does nothing, a hollow stand-in for tests.

Test agenttest-agent

A test agent — runs the test suite so nobody has to remember to.

Test filetest-file

A page with a play button on it — a test file ready to run in the suite.

In code, each is one import — import { Ablation } from "@iconmind/react/icons/ablation" — and the same name in Vue, Svelte, Solid, Preact, React Native, Astro, Blade and Flutter.
