Advanced Multi-Mechanize Virtual User Scripts

``` import mechanize import time

class Transaction(object): def init(self): self.custom_timers = {}

def run(self):
    # create a Browser instance
    br = mechanize.Browser()
    # don't bother with robots.txt
    br.set_handle_robots(False)
    # add a custom header so wikipedia allows our requests
    br.addheaders = [('User-agent', 'Mozilla/5.0 Compatible')]

    # start the timer
    start_timer = time.time()
    # submit the request
    resp = br.open('http://www.wikipedia.org/')
    resp.read()
    # stop the timer
    latency = time.time() - start_timer

    # store the custom timer
    self.custom_timers['Load_Front_Page'] = latency  

    # verify responses are valid
    assert (resp.code == 200), 'Bad HTTP Response'
    assert ('Wikipedia, the free encyclopedia' in resp.get_data()), 'Text Assertion Failed'

    # think-time

    # start the timer
    start_timer = time.time()

    resp = br.submit()  
    resp.read()
    # stop the timer
    latency = time.time() - start_timer

    # store the custom timer
    self.custom_timers['Search'] = latency  

    # verify responses are valid

```

this example will generate an HTTP GET ``` import urllib2 import time

class Transaction(object): def init(self): self.custom_timers = {}

def run(self):
    start_timer = time.time()
    resp = urllib2.urlopen('http://www.example.com/')
    content = resp.read()
    latency = time.time() - start_timer

    self.custom_timers['Example_Homepage'] = latency

    assert (resp.code == 200), 'Bad HTTP Response'
    assert ('Example Web Page' in content), 'Failed Content Verification'

```

this example will generate an HTTP POST containing a SOAP request in its body. The request message (SOAP envelope) is read from a file named 'soap.txt'. ``` import urllib2 import time

class Transaction(object): def init(self): self.custom_timers = {} with open('soap.xml') as f: self.soap_body = f.read()

def run(self):
    req = urllib2.Request(url='http://www.foo.com/service', data=self.soap_body)
    req.add_header('Content-Type', 'application/soap+xml')
    req.add_header('SOAPAction', 'http://www.foo.com/action')

    start_timer = time.time()
    resp = urllib2.urlopen(req)
    content = resp.read()
    latency = time.time() - start_timer

    self.custom_timers['Example_SOAP_Msg'] = latency

    assert (resp.code == 200), 'Bad HTTP Response'
    assert ('Example SOAP Response' in content), 'Failed Content Verification'

```

``` import httplib import urllib import time

class Transaction(object): def init(self): self.custom_timers = {}

def run(self):
    post_body=urllib.urlencode({
        'USERNAME': 'corey',
        'PASSWORD': 'secret',})
    headers = {'Content-type': 'application/x-www-form-urlencoded'}            

    start_timer = time.time()
    conn = httplib.HTTPConnection('www.example.com')
    conn.request('POST', '/login.cgi', post_body, headers)
    resp = conn.getresponse()
    content = resp.read()
    latency = time.time() - start_timer

    self.custom_timers['LOGIN'] = latency

    assert (resp.status == 200), 'Bad HTTP Response'
    assert ('Example Web Page' in content), 'Failed Content Verification'

```

``` import httplib import time

class Transaction(object): def init(self): self.custom_timers = {}

def run(self):
    conn = httplib.HTTPConnection('www.example.com')
    start = time.time()
    conn.request('GET', '/')
    request_time = time.time()
    resp = conn.getresponse()
    response_time = time.time()
    conn.close()     
    transfer_time = time.time()

    self.custom_timers['request sent'] = request_time - start
    self.custom_timers['response received'] = response_time - start
    self.custom_timers['content transferred'] = transfer_time - start

    assert (resp.status == 200), 'Bad HTTP Response'

if name == 'main': trans = Transaction() trans.run()

for timer in ('request sent', 'response received', 'content transferred'):
    print '%s: %.5f secs' % (timer, trans.custom_timers[timer])
