The tests cover the following scenarios: - Applying multiple patch rules to the same file. - Merging `extraPatches` in `applyBuiltInPatches`. - Calling `applyDependencyPatches` multiple times with different inputs. For each test case, the following is verified: - Correct creation and content of the `.ogfile`. - Skipping of already patched files. - Re-application of patches based on the `.ogfile` when `VXRN_FORCE_PATCH` is set. The `patches.ts` file has been modified for better testability, allowing customization of `node_modules` path and built-in patches. A new script `test:deps-patching` has been added to `packages/vxrn/package.json` to run these tests. --- packages/vxrn/package.json | 4 +- packages/vxrn/run-tests.sh | 10 + packages/vxrn/src/utils/patches.ts | 16 +- .../patching-test/testfile.js | 1 + packages/vxrn/src/utils/test-runner.js | 243 ++++++++++++++++++ 5 files changed, 267 insertions(+), 7 deletions(-) create mode 100755 packages/vxrn/run-tests.sh create mode 100644 packages/vxrn/src/utils/test-fixtures/mock-node_modules/patching-test/testfile.js create mode 100644 packages/vxrn/src/utils/test-runner.js diff --git a/packages/vxrn/package.json b/packages/vxrn/package.json index 1fc1a9c41..97fdf68e8 100644 --- a/packages/vxrn/package.json +++ b/packages/vxrn/package.json @@ -54,7 +54,9 @@ "watch": "yarn build --watch", "check": "yarn depcheck", "clean": "tamagui-build clean", - "clean:build": "tamagui-build clean:build" + "clean:build": "tamagui-build clean:build", + "test": "yarn test:deps-patching", + "test:deps-patching": "./run-tests.sh" }, "dependencies": { "@expo/config-plugins": "^8.0.8", diff --git a/packages/vxrn/run-tests.sh b/packages/vxrn/run-tests.sh new file mode 100755 index 000000000..932229f2c --- /dev/null +++ b/packages/vxrn/run-tests.sh @@ -0,0 +1,10 @@ +#!/bin/bash + +# Get the directory where the script is located +SCRIPT_DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" &> /dev/null && pwd )" + +# Navigate to the utils directory where test-runner.js is located +cd "$SCRIPT_DIR/src/utils" || exit 1 + +# Execute the test runner using Node.js +node test-runner.js diff --git a/packages/vxrn/src/utils/patches.ts b/packages/vxrn/src/utils/patches.ts index 99fb6c1dd..caadcfb93 100644 --- a/packages/vxrn/src/utils/patches.ts +++ b/packages/vxrn/src/utils/patches.ts @@ -115,22 +115,26 @@ const getIsAlreadyPatched = (fullFilePath: string) => { _isAlreadyPatchedMap.set(fullFilePath, isAlreadyPatched) return isAlreadyPatched } -const _isAlreadyPatchedMap = new Map() +export const _isAlreadyPatchedMap = new Map() /** * A set of full paths to files that have been patched during the * current run. */ -const pathsBeingPatched = new Set() +export const pathsBeingPatched = new Set() // --- HACK! --- export async function applyDependencyPatches( patches: DepPatch[], - { root = process.cwd() }: { root?: string } = {} + { root = process.cwd(), nodeModulesPath }: { root?: string; nodeModulesPath?: string | string[] } = {} ) { - const nodeModulesDirs = findNodeModules({ - cwd: root, - }).map((relativePath) => join(root, relativePath)) + const nodeModulesDirs = nodeModulesPath + ?
