Start with the Firefox add-on Katalon Recorder. You will probably have to modify the script it generates, but WebDriver is simple. You can also use the Katalon Recorder to test your script locally and make sure it works. Here are some other bits of advice:
There are several reasons why the agents may be slower than on your laptop:
Our primary goal is to provide consistent performance in a given location. Between locations, we try to keep everything consistent except the network.
When in doubt, run several sessions from the same location to confirm that the session duration is stable, and do the same from a different location to compare the results.
We don't have special support at this time, but if you can write Python code to do something using the standard libraries, you can do that in your script.
One way would be to use a try-catch clause and wait for an alert as shown below:
from selenium.common.exceptions import TimeoutException # Handle an alert pop-up try: WebDriverWait(driver, 2).until(EC.alert_is_present()) alert = driver.switch_to_alert() alert.accept() #print "alert accepted" except TimeoutException: print 'No alert pop-up'
For file uploads, you need to either download a file or generate one in your script (we have no way of letting you upload things to the sandbox at the moment). Next, set the path of the input element to the absolute path of the file to upload.
Below is a working example that uploads a generated file with random content to https://encodable.com/uploaddemo/:
import random from selenium import webdriver from selenium.webdriver.common.by import By from selenium.webdriver.common.keys import Keys from selenium.webdriver.support import expected_conditions as EC from selenium.webdriver.support.ui import WebDriverWait import time driver.implicitly_wait(10) # Generate a file with random numbers generated_file_name = "/tmp/generatedfile.txt" with open(generated_file_name, "w") as generated_file: for _ in range(500): generated_file.write(str(random.randint(0,9))) driver.get("https://encodable.com/uploaddemo/") driver.find_element_by_css_selector("input.upform_field.file.required") \ .send_keys(generated_file_name) driver.find_element_by_css_selector("#uploadbutton") \ .click(); # Wait for "Your upload is complete" text to show up upload_complete = WebDriverWait(driver, 10).until( EC.presence_of_element_located((By.CSS_SELECTOR, "dt.first"))) # Check that things worked as expected" assert upload_complete.text == "Your upload is complete:" txt=driver.find_element_by_xpath("//dt[contains(text(),'Your upload is complete:')]") print(txt.text)
As far as downloading files, you can definitely get the browser to download something, but from there you won't able to inspect the downloaded file from your script because we have no way to extract this file from the agent to the sandbox.
Each script is executed in a Docker container created and destroyed for each run. The script connects to a Windows agent to drive its web browser. For isolation, we clear the browser caches, history, and DNS cache between runs.
In both cases, we don't write to the disk, so if a hacker could steal a disk from the data centers we use, they might be able to recover something, but this would be a very sophisticated and expensive attack.
We don't baseline per job per GEO currently. We do baseline the overall page times per GEO alongside the current RUM metrics.
You can't schedule a maintenance window per se, but if you know when your maintenance windows are going to be scheduled, then you can set up your schedules so that no jobs will be executed during that window. Alternatively, if you don't know ahead of time when the maintenance windows are going to be scheduled, you can always go in manually and hit the Disable button on the jobs before the maintenance starts and then re-enable them afterward.
You can set the height and width of the browser window using the set_window_size(width, height, windowHandle='current') method. For example, if you want to set the window size to 800x600 pixels, insert this method into your Synthetic Script:
We give the options of alerting after a retry that is also over the threshold, immediate alert with no retry and alerting after n measurements are over the threshold.
Each page is analyzed individually. If any of them is over the threshold, the alert is generated.
We do confirm a warning and error when detected. We generate events, however, at every state: issue detected, confirmed, ongoing, and cleared, and give you the option of being notified of events you care about.
We currently have 27 locations, and we’ll be adding more based on customer demand. Using the public cloud lets us deploy anywhere we can find a good cloud provider.
Availability (parts-per-million) is computed as: (# succeeded / # attempted) * 1,000,000 and represented in per million, instead of percent, because controller metrics are always integer-valued. If we had used percent, the most precise availability we could represent would be 100%, 99%, 98%. Not, for example, 99.99%.
To convert per-million to percent, just divide by 10,000. For example, if the availability (ppm) is 999,800, then the availability (%) is 99.98.
Most screens convert to percent before showing, but "raw data" screens like the metric browser show the value per-million.
We offer three locations with static IPs that you can use to test internal applications from external locations.
Firefox runs version 41.0.1, and Chrome runs version 48 (updated on 2017-03-09). Please note that browser versions are subject to change in the future.
Browser versions are generally locked; however, we can upgrade within 1-2 weeks as required.
Browser extensions like Flash and Silverlight (which are being phased out) can't be monitored by stock Selenium, which is what we support. Many in the community have extended Selenium with APIs to do this.
We don't currently support the use of 3rd-party libraries in our runtime.
Browser tests are run on single-core VMs with 4 GB of RAM, although the hardware may vary slightly per location. To ensure consistent performance results, the VMs only run one job at a time.
No. There isn't a standard accepted tool that would do that, and honestly, this is just a bad idea. These scripts do have a maintenance cost, and a pure machine conversion between two languages is just going to make this more difficult. Not to mention debugging in the first place, unless things work out of the box, which is not very likely, the machine translation is going to be really hard to debug.
You can use any library that is part of the standard distribution of Python 2.7. In addition, the following libraries are available:
There are no size limits for test scripts. Please be aware, however, that larger files will use more time (more "expensive").
We do not have a timeframe for mobile yet.
