 To see the effect of your changes and to test them, push your changes in a branch and then look at the [Actions output](https://github.com/github/codeql-action/actions) for that branch.  You can also exercise the code locally by running the automated tests.

+### Running the action locally
+
+It is possible to run this action locally via [act](https://github.com/nektos/act) via the following steps:
+
+1. Create a GitHub [Personal Access Token](https://github.com/settings/tokens) (PAT).
+1. Install [act](https://github.com/nektos/act) v0.2.10 or greater.
+1. Add a `.env` file in the root of the project you are running:
+
+  ```bash
+  CODEQL_LOCAL_RUN=true
+
+  # Optional, for better logging
+  GITHUB_JOB=<ANY_JOB_NAME>
+  ```
+
+1. Run `act -j codeql -s GITHUB_TOKEN=<PAT>`
+
+Running locally will generate the CodeQL database and run all the queries, but it will avoid uploading and reporting results to GitHub. Note that this must be done on a repository that _consumes_ this action, not this repository. The use case is to debug failures of this action on specific repositories.
+
 ### Integration tests

 As well as the unit tests (see _Common tasks_ above), there are integration tests, defined in `.github/workflows/integration-testing.yml`.  These are run by a CI check.  Depending on the change you’re making, you may want to add a test to this file or extend an existing one.

Andrew Eisenberg	42235cc048	Allow the codeql-action to be run locally (#117 ) * Allow the codeql-action to be run locally This change allows the codeql-action to be run locally through [act](https://github.com/nektos/act). In order to run the action locally, you need to do two things: 1. Add the `CODEQL_LOCAL_RUN: true` environment variable. The only way I could figure out how to do this was to add it directly in the workflow file in an `env` block. It _should_ be possible to add it through a `.env` file and pass it to `act`, but I couldn't get it working. 2. Run this command `act -j codeql -s GITHUB_TOKEN=<MY_PAT>` Setting the `CODEQL_LOCAL_RUN` env var will fill in missing env vars that the action needs, but isn't set by `act`. It will also avoid making api calls to github that would fail locally. This is a refactoring discussed in https://github.com/github/dsp-codeql/issues/36	2020-08-04 14:35:20 -07:00
