A reg-suit plugin to determine the snapshot key with given values.

npm i reg-simple-keygen-plugin -D

{
  expectedKey: string;
  actualKey: string;
}

• expectedKey - Required - Identifier key value of the expected(previous) snapshot.
• actualKey - Required - Identifier key value of the actual(current) snapshot.

Using reg-suit's replacing environment values feature, you can use Git commit sha1 hashes provided with CI service. The following example allows reg-suit to compare HEAD of the master branch with the PR's commit.

# .travis.yml
script:
  - export EXPECTED_KEY=$(git rev-parse origin/master)
  - export ACTUAL_KEY=$TRAVIS_COMMIT # set by TravisCI
  - reg-suit run

  // regconfig.json
  "plugins": {
    "reg-simple-keygen-plugin": {
      "expectedKey": "${EXPECTED_KEY}",
      "actualKey": "${ACTUAL_KEY}"
    },
    ...
  }
