compiler unit testing

The compiler unit testing for ace2.0.

Usage

Here are simplified instructions of how to get started. The following commands work both on Windows and Linux platforms.

1. Install

First, enter the root directory of the compiler:

$ cd compiler/

And then install the npm dependencies(You must have node&npm installed):

$ npm install

Note: If some errors occur, delete the generated package node_modules, config npm proxy and run npm install again.

npm config set proxy http://username:password@server:port
npm confit set https-proxy http://username:password@server:port

2. Quick Start

First, create a new test file or directory in compiler/test. Write source code in variable 'source', and write expected code in variable 'expectResult':

// source code
export const source: string = `...`
// expected code
export const expectResult: string = `...`

In the root directory of compiler/:

$ npm run test

All files in the compiler/test will be tested.

3. Example

1. Create a new test directory foo in compiler.
2. Create a new test file bar.ts in compiler/foo.
3. In the file bar.ts, write the following lines:

export const source: string = `
struct MyComponent {
  build() {
  }
}`

export const expectResult: string =
`class MyComponent {
  build() {
  }
}
`

4. In the root directory of compiler/:

$ npm run test

5. All files in the compiler/test will be tested. The output is like the following lines:

 ✓ bar
  1 passing (1ms)

Note: If the actual building result is different from the expected result and the output is like the following lines, you should check the error:

  1) bar

  0 passing (1ms)
  1 failing

  1) compiler
       bar:

      AssertionError: expected 'class MyComponent {\n    build() {\n    }\n}\n' to deeply equal 'class MyComponent {\n    build() {\n    \n}\n'
      + expected - actual

       class MyComponent {
           build() {
      -    }
      +
       }
