Browser Testing

Problem

You want to test webpy applications.

Solution

Use the 'browser' module.

urls = (
    '/', 'Index',
    '/login', 'Login',
)

class Index:

    def GET(self):
        return """
        <html><body>
        <a href="/login">Login</a>
        </body></html>"""

class Login:
    
    def GET(self):
        return """
        <html><body>
        <form name="login" action="">
        Name: <input type="text" name="username"><br>
        PW: <input type="password" name="password"><br>
        </form>
        </body><html>
        """

    def POST(self):
        i = web.input()
        return "Welcome " + i.name
         

app = web.application(urls, globals())

b = app.browser()
b.open('/')
b.follow_link(text='Login')

b.select_form(name='login')
b['username'] = 'joe'
b['password'] = 'secret'
b.submit()

assert b.path == '/login'
assert 'Welcome joe' in b.get_text()

It is also possible to use the browser module for crawling or testing existing websites.

b = web.Browser()
b.open('http://webpy.org')
b.follow_link(url_regex='login')

b.select_form(name='login')
b['username'] = 'joe'
b['password'] = 'secret'
b.submit()

assert b.path == '/'
assert 'Log Out' in b.get_text()
