## API
TODO
First, this library must by instantiated by calling its constructor:
```javascript
const Bluefox = require('bluefox');
const wait = new Bluefox();
```
Wait conditions are then defined by chaining together `actions` to form an `expression`. An `expression` is executed by consuming it as a Promise (`expression.then(...)`, `await expression`, etc).
During execution the `current value` is consumed and/or modified by the actions that make up the expression; the output of an action is used as the input of the next action. The `current value` must be either:
* `null`
* A `WindowProxy` instance
* A `HTMLDocument` instance
* An `Element` instance
* An array of `WindowProxy`, `HTMLDocument`, `Element` instances
For example the expression `await wait.target(document.body).selector('div').selector('p')` returns the first `<p>` element that is a descendant of the first `<div>` element that is the first descendant of the document's `<body>` element.
Some actions may cause the execution to remain pending based on their input value. For example `await wait.target(document).documentInteractive()` delays the fulfillment of the execution until the HTML of the document has been completely parsed (DOMContentLoaded).
An expression is immutable. This lets you execute it multiple times or base a new expression of an existing one.
### Available actions
#### .timeout(duration)
This action sets the timeout for all subsequent actions. If the timeout duration is reached, the Promise of the `execution` rejects with an `Error`. If this action is not specified, a default timeout of 30 seconds is used.
```javascript
await wait.target(document).documentComplete(); // 30 second timeout
await wait.target(document).timeout('1s').documentComplete(); // 1 second timeout
await wait.target(document).timeout(1500).documentComplete(); // 1.5 second timeout
```
#### .target(value)
The target action is used to simply set the `current value`. It is almost always used as the first action in the chain.
```javascript
await wait.target(window).selector('html')
await wait.target(document).documentInteractive()
await wait.target(document.body).check(body => body.classList.contains('foo'))
await wait.target([someElement, anotherElement]).selectorAll('p')
```
#### .amount(minimum, maximum)
This action causes the execution to remain pending if the `current value` has less than `minimum` or more than `maximum` objects. If this action is not specified, the execution waits until `current value` contains 1 or more objects. The `current value` is not modified by this action.
```javascript
await wait.target(window).selectorAll('img.thumbnail') // 1 or more
await wait.target(window).selectorAll('img.thumbnail').amount(1, Infinity) // 1 or more
await wait.target(window).selectorAll('img.thumbnail').amount(1) // exactly 1
await wait.target(window).selectorAll('img.thumbnail').amount(0) // exactly 0
await wait.target(window).selectorAll('img.thumbnail').amount(2, 4) // 2 or 3 or 4
```
#### .selector(cssSelector)
Return the first `Element` (or `null`) that matches the given CSS selector and is a descendant of any objects in `current value`.
```javascript
const link = await wait.target(window).selector('a.someLink');
link.click();
const anotherLink = await wait.target([someElement, anotherElement]).selector('a.someLink');
anotherLink.click();
```
#### .selectorAll(cssSelector)
Return all `Element` instances (as an array) that match the given CSS selector and are a descendant of any objects in `current value`.
```javascript
const links = await wait.target(window).selectorAll('.todoList a');
links.forEach(link => link.click());
```
#### .xpath(expression)
Execute the given XPath `expression` setting the `current value` as the XPath `context node` and return the first `Element` instance that matches. A result that is _not_ an `Element` will result in an error.
```javascript
await wait.target(window).xpath(`.//h1[./@id = 'introduction']`);
await wait.target(document.body).xpath(`./p`);
```
_Note: XPath expressions often cause more overhead than CSS Selectors._
#### .xpathAll(expression)
Execute the given XPath `expression` setting the `current value` as the XPath `context node` and return the all `Element` instances that match. A result that is _not_ an `Element` will result in an error.
```javascript
await wait.target(window).xpathAll(`.//a[@href]`).amount(10, Infinity);
await wait.target(document.body).xpathAll(`./p`).amount(0);
```
_Note: XPath expressions often cause more overhead than CSS Selectors._
#### .documentInteractive()
This action causes the execution to remain pending if any of the `HTMLDocument` instances in `current value` have a `readyState` that is not `"interative"` nor `"complete"`. If the `current value` contains any `Element` instances, the check will be performed on their `ownerDocument`. The `current value` is not modified by this action.
```javascript
window.addEventListener('DOMContentLoaded',
() => console.log('documentInteractive!')
);
await wait.target(document).documentInteractive();
await wait.target(document.body).documentInteractive();
```
#### .documentComplete()
This action causes the execution to remain pending if any of the `HTMLDocument` instances in `current value` have a `readyState` that is not `"complete"`. If the `current value` contains any `Element` instances, the check will be performed on their `ownerDocument`. The `current value` is not modified by this action.
```javascript
window.addEventListener('load',
() => console.log('documentComplete!')
);
await wait.target(document).documentComplete();
await wait.target(document.body).documentComplete();
```
#### .delay(duration)
This action causes the execution to remain pending until the given `duration` has passed (since the start of the execution).
```javascript
await wait.delay('2s'); // 2000ms
await wait.delay(2000); // 2000ms
```
#### .isDisplayed()
This action removes all elements from `current value` that are not currently displayed on the page. An element is "displayed" if it influences the rendering of the page. _(Specifically, `element.getBoundingClientRect()` returns a non zero `width` and `height`)._
```javascript
await wait.selector('.submitButton').isDisplayed()
await wait.selectorAll('.gallery img').isDisplayed().amount(10, 50);
```
#### .check(callback)
This action calls the given `callback` function for each item in `current value` and removes all items for which the callback returns `false`.
```javascript
await wait.selector('p.introduction').check(n => /hello/.test(n.textContent))
await wait.selector('img').check(n => img.complete).amount(10, Infinity)
```
