+# pr-lint-action
+
+A GitHub Action that verifies your pull request contains a reference to a ticket.  It will optionally check the PR title contains `[PROJ-1234]` and the branch contains PROJ-1234 or PROJ_1234.  This helps ensure every PR gets mapped to a ticket in Jira!
+
+## Usage
+
+Add `.github/pr-lint.workflow` with the following:
+
+```
+workflow "PR Lint Action" {
+  on = "pull_request"
+  resolves = "PR Lint Action"
+}
+
+action "PR Lint Action" {
+  uses = "vijaykramesh/pr-lint-action@master"
+  secrets = ["GITHUB_TOKEN"]
+}
+```
+
+## Configuration
+
+Configure by creating a `.github/pr-lint.yml` file:
+
+For example:
+
+```yml
+projects: ['PROJ', 'ABC']
+check_title: true
+check_branch: true
+ignore_case: true
+```
+
+## Testing
+
+Run `jest test` to test:
+
+```
+PASS  ./index.test.js
+  pr-lint-action
+    ✓ fails if check_title is true and title does not match (106ms)
+    ✓ passes if check_title is false and title does not match (67ms)
+    ✓ passes if check_title is true and title matches (61ms)
+    ✓ fails if check_branch is true and branch does not match (57ms)
+    ✓ passes if check_branch is false and branch does not match (59ms)
+    ✓ passes if check_branch is true and branch matches (57ms)
+    ✓ fails if check_branch and check_title is true and title does not match (59ms)
+    ✓ fails if check_branch and check_title is true and title does not match (59ms)
+    ✓ passes if check_branch and check_title is true and both match (58ms)
+    ✓ passes if ignore_case and lower case title/branch (55ms)
+    ✓ fails if not ignore_case and lower case title/branch (109ms)
+```
