A question came up on stack overflow about how to route Watir through an authenticating proxy within your script. The problem here is that you cannot auto authenticate to a proxy server using Chrome –proxy-server=my.proxy.com:3128 or using Firefox. Chrome will always prompt you for a user name and password on an authenticating proxy when it starts up [...] If you’re using an RBU or VU you may need to extract content from the previous response. For example, enumerate a link to a PDF file for subsequent download. The BrowserMob interface has a handy findRegexMatches method you can call as follows: var link = browserMob.findRegexMatches(selenium.getHtmlSource(), ‘href="(.+?pdf)"’); It takes a string input and [...] If you come from the commercial toolset mindset, you might be interested in how we achieve think time and pacing when using alternatives such as BrowserMob. Think Time Can you afford a slow landing page? Google AdWords page quality criteria are many, a prominent check being your landing page load time. A slow load time can lead to a lower quality score. Make sure you’re not wasting effort on advertising campaigns. Altentee uses BrowserMob to help check website performance for clients from multiple locations. You [...] There’s been a bit of buzz lately where MySQL databases have been compromised and user passwords being stored in plain text. Bad fu. It’s pretty simple to encrypt passwords in MySQL, here’s how you do it. A common requirement when load testing is to populate subsequent requests with dynamic data from previous requests. If you’re thinking about using a database to store static test data, such as usernames, paswords, credit card numbers etc then read on to find out how to extract this data at runtime and populate JMeter variables. No, not the song but my adage for 2010 in my approach to performance testing in general. Readers of my old blog 90kts.com may have noticed the recent change to altentee.com. In 2009 I helped setup a boutique testing company called Altentee Pty Ltd. Read on for a quick advertisement about this new initiative … So I’ve been working on a system where the MySQL instance on EC2 sporadically locks up (mysqld is zombied) during a snapshot process =) Essentially the EC2 snapshot is triggered like this: system("xfs_freeze -f /vol") and die; This method is based on advice from here Notice I [...] Well the subject goes without saying. I’ve been working on WinXP again lately and when I’m not around my favourite text editor on the mac (TextMate) I opt for SCiTE on windows. The following settings I find useful for this simple but powerful text editor. YMMV. In my last post I made a tongue-in-cheek observation that load testing really doesn’t work by today’s perceived standards for web automation and testing. Part of my grievance for that was based on frustration in dealing with different load testing platforms. Not frustration born out of incompetence, more the frustration born out writing tests for increasingly [...] |
