Nullean.Snapshots.Cli 0.13.0

Nullean.Snapshots.Cli

snap, the native AOT command line tool for Nullean.Snapshots: review, diff, accept and reject pending snapshots, find orphaned ones, and run browser journeys and .http files without a test run.

Install

dotnet tool install --global Nullean.Snapshots.Cli

Quick start

snap                               # walk through what changed: accept, reject or skip each snapshot
snap status --json                 # pending snapshots; exits 1 when there are any
snap diff CatalogTests/Renders     # full key, unique suffix, or glob
snap accept CatalogTests/Renders   # only after reading the diff
snap reject --all                  # delete received files, keep verified
snap orphans                       # verified files the last test run did not use

Without installing it: dnx Nullean.Snapshots.Cli accept CatalogTests/Renders.

Journeys, .http files and two sites

snap journey run 'tests/Shop.Tests/journeys/**/*.journey' --base-url http://localhost:5000/
snap http run 'tests/Shop.Tests/http/**/*.http' --env dev --var host=http://localhost:5000
snap journey compare 'journeys/**/*.journey' --baseline https://prod.example.com/ --target https://preview.example.com/
snap http compare 'http/**/*.http' --baseline https://api.example.com --target https://api-preview.example.com

compare fails only on differences no rule in the checked-in {file}.differences expects; --record appends the rules that would explain a failure instead.

Accepting an inline snapshot edits the string literal in the test's .cs file, so read git diff of the test files as well as the verified ones.
