LoadRunner and IE 8 Compatibility

[Harish Majithiya]

Hi All,

 

We want to do performance testing of an application which is going to be used with IE 8.

 

1. I came to know Load runner does not support IE 8. Is it really so? Can anyone give me the link to HP Documents where it's indicated?

2. Runtime settings "Browser emulation" does not display version IE 8. - LR 9.5

3. For some applications it allows recording using IE 8, but even if it allows recording when we run it, are we really simulating IE 8.

4. What are the performance parameters different for different IE version. I mean what could be the reason an application would give good performance for IE 6 and not for IE 8.

 

Thanks in advance..!!!

1. Open the "Readme" file from the installation directory to find compatibility related information. And YES laodrunner 9.5 doesn't support IE 8. But, it doesn't entirely mean LR won't record if you use IE 8. In most cases it does work, however, if there are lots of web 2.0 style client side scripting implemented in your application, then LR might give you problems while recording a script and HP support won't come to rescue.

 

 

2. Lost you there...

 

3. LoadRunner is not designed to accurately emulate any browser per se(Be it, IE 6/7/8). Except for cache related settings and sending-receiving information it doesn't do anything more fancy and the good news is it doesn't have to.

 

4. Who says that an application gives better performance in IE 6 when compared to IE 8? Whats the rationale behind it? And, where does LR come in the picture?

Hi,

LoadRunner 11 will support IE 8 (officially).

Thanks and Regards,

1. Check out your system requirements for the version of LoadRunner you
have in use. These requirements docs will note the supported type and
version of browser for your release of LoadRunner.

2. Go to your web server logs and read a couple of pieces of the log.
Then go to the options for browser emulation and select custom string.
Visualize the information presented within the log on the web server and
then change your browser to represent "windows 2015, IE20 Engineering
Alpha, do not use outside of Microsoft." Run your virtual user.
Look in the web server logs for your session information. Make sense?

The only real reason that browser version makes one whit of difference
is if your backend application rendering engine makes different choices
for rendering the HTML based upon VERSION AND TYPE of browser. I have
yet to find both of those conditions in place, instead the decision is
usually "in gross" in the topic of specific rendering for non-HTML
standard for IE and true HTML standard for non-IE. For additional
reading on this topic I recommend the reference "PHP and MYSQL for
Dummies" with particular attention paid to conditional rendering for IE.

3. The server really has no idea what browser is on the other end of
the conversation beyond how the browser and client operating system
announces itself. See announcement via custom string in 2 above.

4. Isn't this really a question you should be answering with a
functional test before you run a performance test? If it will not work
for one then it will never work for many. This question would suggest
that you may be co-mingling your functional and performance tests, which
is generally not recommended.

By that time, IE 11 will come.
