# @coon-js/siesta-lib-helper  [](https://badge.fury.io/js/@coon-js%2Fsiesta-lib-helper) 
Easy setup for testing Ext JS with [Siesta](https://bryntum.com).
#### About
This npm-package provides a collection of utility- and helper-methods for [Siesta](https://bryntum.com)
and [Ext JS](https://sencha.com).
## Installation
To use this package with Ext JS-projects, include the package as a `devDependency`:
```bash
$ npm i --save-dev @coon-js/siesta-lib-helper
```
A binary of `@coon-js/siesta-lib-helper` can then be called:
`
npx siesta-lib-helper
`
## Usage
### Using the BoilerPlate.js for setting up Ext JS Browser Environment
The `BoilerPlate.js` contains code that automatically creates an Ext JS-testing environment.
To use the BoilerPlate, it should be sufficient to copy the `index.extjs-browser.html` into the target directory
where your tests should run. Paths should be adjusted accordingly, if your testing environment does not
match the following structure:
(In this example, `index.extjs-browser.html` will be placed into `tests`)
```
./[MODULE_ROOT]
./node_modules
./tests
```
To simplify setting up your testing environment, `siesta-lib-helper` is available as a cli-programm that
will copy a `tests.redirect.html`- and a `index.extjs-browser.html`-file into your module:
```shell
$ npx siesta-lib-helper
```
```
./tests/index.extjs-browser.html
./tests.redirect.html
```
Note: `tests.redirect.html` serves as a redirect in case your local web server requires a file being specified as the index of the
document-root. It is not require to properly create the Ext JS-Testing-Browser.
### getPaths()
The following example shows how to use a _test.config.js_ for configuring the tested environment to be used
with [Siesta.Harness.Browser.ExtJS](https://www.bryntum.com/docs/siesta/#!/api/Siesta.Harness.Browser.ExtJS).
The corresponding builds and paths for the Ext JS-library were automatically created with [@coon-js/extjs-link](https://github.com/coon-js/extjs-link).
_index.html_
```html
example
```
_index.js_ contains the instantiation of the browser-class and configures the Siesta-Browser with the
required options:
_index.js_:
```javascript
import groups from "./groups.config.js"; // contains test-structure
import testConfig from "./tests.config.js";
import {getPaths} from "../node_modules/@coon-js/siesta-lib-helper/dist/siesta-lib-helper.runtime.esm.js";
const
browser = new Siesta.Harness.Browser.ExtJS(),
isModern = window.location.href.indexOf("toolkit=modern") !== -1,
paths = getPaths(testConfig, isModern);
browser.configure(Object.assign({
title: "example - " + (isModern ? "modern" : "classic"),
isEcmaModule: true,
disableCaching: true
}, paths));
browser.start(...groups);
```
In this example, the configuration looks like this. While the ```loaderPath``` is most of the time depending
on the existing resources you want to include in your tests, the preload of the Ext JS-library is mandatory:
_tests.config.js_
```javascript
export default {
loaderPath: {
"Ext.Package": "../node_modules/@coon-js/extjs-package-loader/packages/package-loader/src/Package.js",
"Ext.package": "../node_modules/@coon-js/extjs-package-loader/packages/package-loader/src/package",
"coon.core.overrides.core": "../overrides",
"coon.core.fixtures": "./fixtures",
"coon.core": "../src/",
"coon.test": "./src"
},
preload: {
css: {
modern: [
"./build/extjs-link/extjs/modern/theme-triton/resources/theme-triton-all-debug.css"
],
classic: [
"./build/extjs-link/extjs/classic/theme-triton/resources/theme-triton-all-debug.css"
]
},
js: ["../node_modules/@l8js/l8/dist/l8.runtime.umd.js", {
modern: "./build/extjs-link/extjs/modern/ext-modern-all-debug.js",
classic: "./build/extjs-link/extjs/classic/ext-all-debug.css"
}]
}
};
```
### configureWithExtJsLinkPaths()
A helper method to inject the configuration generated by [@coon-js/extjs-link](https://npmnjs.org/@coon-js/extjs-link)
into a configuration as defined by a ```tests.config.js```-file, then passing it to [getPaths()](#getPaths()).
Basically, toolkit-groups defined in both files get merged.
_index.html_
```html
example
```
_index.js_ contains the instantiation of the browser-class and configures the Siesta-Browser with the
required options:
_index.js_:
```javascript
import testConfig from "./tests.config.js";
import groups from "./groups.config.js";
import {configureWithExtJsLinkPaths} from "../node_modules/@coon-js/siesta-lib-helper/dist/siesta-lib-helper.runtime.esm.js";
const
browser = new Siesta.Harness.Browser.ExtJS(),
isModern = window.location.href.indexOf("toolkit=modern") !== -1,
paths = await configureWithExtJsLinkPaths(testConfig, "../.extjs-link.conf.json", isModern);
console.log(paths);
browser.configure(Object.assign({
title: "extjs-lib-core - " + (isModern ? "modern" : "classic"),
isEcmaModule: true,
disableCaching: true
}, paths));
browser.start(...groups);
```
