breeze-client tests

These tests were rewritten using Jest. See the Jest Getting Started guide and Jest Troubleshooting for more info.

Running the tests

Run using npm test to run all the tests.

Run using npm test -- query-basic.spec.ts to run just the tests in query-basic.spec.ts. Use a similar pattern for other files.

Edit a spec file and replace test("test name"...) with test.only("test name"...) to run a single test.

The server

Most of these tests require a server that implements the NorthwindIB persistence layer and responds to the query and save requests.

Generally we use a .NET server from the breeze.server.net repo, such as Test.AspNetCore8.EFCore8.sln in Test.AspNetCore.EFCore

One can also use the BreezeExpressDemo server from breeze-sequelize.

Debugging the tests

In Chrome

See Jest Troubleshooting for info on debugging in Chrome.

From VSCode

Add the following run configuration:

    {
      "name": "Debug Jest Tests",
      "runtimeExecutable": "{your path to node}/node.exe",
      "type": "node",
      "request": "launch",
      "runtimeArgs": [
        "--inspect-brk",
        "${workspaceRoot}/spec/node_modules/jest/bin/jest.js",
        "--runInBand"
      ],
      "console": "integratedTerminal",
      "internalConsoleOptions": "neverOpen",
      "cwd": "${workspaceRoot}/spec"
    }

Then you can set breakpoints in VSCode.

Note that the tests run the breeze code installed in /node_modules/breeze-client, so you'll need to set the breakpoints in spec\node_modules\breeze-client\bundles\breeze-client.umd.js, not in the source code.

Old BreezeJs tests not migrated

See information about the legacy breeze tests in BUILD.md.

Note that the following test suites were NOT migrated from old BreezeJs - we may consider moving them at some later time.

  • AjaxAdapterTests - mostly tested old adapters
  • RawODataTests - tests using old ODATA query syntax
  • QueryNonEFTests - querying against a non database backend
  • SaveTransactionTests - specific tests using different .NET Transaction models
  • ClassRewriteTests - tests involving legacy pre ES5 constructs
  • TPT and TPH inheritence tests
  • KO and Mongo specific tests
