Provide a REPL for taiko

[zabil]

Package taiko as a command line tool and library.

Modify taiko.js

• Add shebang

#! /usr/bin/env node

• Link it to /usr/bin/taiko after npm -g install taiko

Initialize the REPL using

$ taiko

Implement custom commands for taiko api

#! /usr/bin/env node

const repl = require('repl');

// Just an example. Implement it inside taiko.js
const _ = require('./taiko')

const server = repl.start({
    prompt: '>> '
});

server.defineCommand('openBrowser', {
    help: 'Opens a browser',
    async action() {
        await _.openBrowser({
            headless: false
        });
        this.displayPrompt();
    }
});

server.defineCommand('goto', {
    help: 'Goto a URL',
    async action(url) {
        await _.goto(url);
        this.displayPrompt();
    }
});

server.defineCommand('click', {
    help: 'Goto a URL',
    async action(item) {
        await _.click(item);
        this.displayPrompt();
    }
});

Can be run as

$ taiko
>> .openBrowser
>> .goto http://getgauge.io
>> .click Get Started

action The function to execute, optionally accepting a single string argument.

The command callback action can only take one string parameter (documentation). I am not sure how the following would be possible

click(button('Alert'));
click($('id'));
write('Hooks', into(field));

[zabil]

This is now changed to a REPL that understands await e.g

>> openBrowser()
>> goto("http://getgauge.io")
>> click("Get Started")

[kashishm]

Implemented.

Test cases

• I should be able to initialize REPL using taiko command
• Should be able to initialize it from a project using taiko

On windows global installation of taiko is successful.
I am able to initialize taiko from a project
However REPL is not getting initialized using the taiko command outside the project directory.

[sswaroopgupta]

After REPL is initialized, I have to explicitly close the browser. Only then the command prompt is getting initialized.

Furthermore, .exit does not closeBrowser automatically.

Note I am working on Windows OS

@sguptatw With the latest, it won't open the browser on running taiko command.
