nightwatch-data-driven

Provides tool for emulating data driven tests in Nightwatch.js.

#### Installation

``sh
npm i nightwatch-data-driven --save
`

#### Example 1: Simple usage

`js
import DataDrivenTest from 'nightwatch-data-driven';
import {authConfig} from '../configs/auth';

var test = {
after: function (browser) {
browser.init();
},
'Valid credentials => successfull login': function (browser) {
// . Initialize DataDrivenTest with browser and AAA function
// and call it for a set of test cases
new DataDrivenTest(browser, function(data, name){
// . Arrange
browser.logout();
// . Act
browser.page.login().loginAndWaitForRedirect(data.email, data.pass);
// . Assert
browser.page.workspace().assertIsCurrentPage(name);
})
.forCases({
"Valid credentials": {email: authConfig.main.EMAIL, pass: authConfig.main.PASS},
"Ignore leading space in email": {email: ' ' + authConfig.main.EMAIL, pass: authConfig.main.PASS},
"Email in upper case": {
email: authConfig.main.EMAIL.toUpperCase(),
pass: authConfig.main.PASS,
disabled: true
}
});
},
after: function (browser) {
browser.end();
}
};
export = test;
`

#### Example 2: Building and reusing of "test blanks"

`js
import DataDrivenTest from 'nightwatch-data-driven';
import {mother} from '../mother';

// . Create "test blank"
let submitLoginForm = new DataDrivenTest()
.withArrange(function(cb) {
this.browser.logout(cb)
})
.withAct(function(dt) {
this.browser.page.login().section.loginForm.fillAndSubmit(dt.email, dt.pass)
});

var test = {
before: function (browser) {
browser.init();
// . Initialize "test blank" with browser
submitLoginForm.withBrowser(browser);
},
'Login is invalid email: show error': function (browser) {
// . Use "test blank" with specific assertion and test cases
submitLoginForm
.withAssert((dt, nm) => browser.page.login().assertNoProgress(nm))
.forCases({
"1. ": {email: "a", pass: mother.Valid.PASS},
"2. ": {email: "@b", pass: mother.Valid.PASS},
"3. ": {email: "@b.", pass: mother.Valid.PASS},
"4. ": {email: "@b.c", pass: mother.Valid.PASS},
"5. ": {email: "a@b", pass: mother.Valid.PASS},
"6. ": {email: "a@b.", pass: mother.Valid.PASS},
"7. ": {email: "a@b.c", pass: mother.Valid.PASS},
"8. ": {email: "й@ц.ук", pass: mother.Valid.PASS},
});
},
'Login is valid email: show progress': function (browser) {
// . Use "test blank" with specific assertion and test cases
submitLoginForm
.withAssert((dt, nm) => browser.page.login().assertProgressDisplayed(nm))
.forCases({
"1. ": {email: "a@b.cd"},
"2. ": {email: "1#$%&'*+/=?^-_{|}~.a@b.cd"},
"3. ": {email: "a@1-b.cd"},
"4. ": {email: "a@b.12"}
});
}
}
export = test;
```
