Our test code is written in C# .NET 4, using libraries that will make HTTP calls to the server. We run the tests via NUnit. Is it possible for usto gettest coverage for theserver code from the NUnit test runs? If so, how should we set it up (a rough outline will do, I will search the details based on the ideas you've specified). Hope to see a reply soon. Thank you in advance.Re: Think Time, Master/Slave, etc.Hi Alex, Thank you for the reply, especially for #1. I now know what items I need to look into. For the recommended configuration, I guess I've overlooked the details here: http://www.automatedqa.com/support/viewarticle/11379/#Requirements.Runtime Graphs1. Why are the runtime graphs not saved along with the test logs, per run? It gets overwritten each time I run the load test but I don't want that. I want to be able to review and compare each run in one centralized location. 2. Can we export the graph somewhere? Print screen is not desired because I don't want to screen capture each time interval.How to modifying traffic through script but retain concurrencyhttp://www.automatedqa.com/support/viewarticle/17275/ sounds like it's saying that when the test is running, I should not use scripting to modify the traffic because concurrency will then be lost. I need to write load test for export PDF. The application keeps on getting update status from the server until the PDF is completely exported. I don't know how many updates it needs until this process is done, so I can't really modify the test before hand. Do you have any recommendations on how to approach this problem? Another question is variable parameterization, using this does not remove concurrency, correct?Re: Think Time, Master/Slave, etc.Please respond. I need to understand this.Think Time, Master/Slave, etc.Hi, 1) I was reading up on more load testing information and was told that "If an agent computer has more than 75% CPU utilization, or has less than 10% of physical memory available, it is overloaded." Is this correct? So if I want to simulate 3000 concurrent users, I would need to set up a master/slave configuration for load testing using the network suite? Usually, how many virtual users should be ran from1 client computer, under what specifications? 2) I read http://msdn.microsoft.com/en-us/magazine/cc188783.aspx#S3, but I still don't understand how 1 virtual user translates to 10 - 15 real users. For example, I have a task for export PDF. I assign that to 1 virtual user, if I run that task for 15 virtual users, that will still be 15 concurrent export PDF at the same point in time, how does it translate to 10 * 15 real user performing the export PDF? So, according to that article, think time should not be present in load tests? How do I verify that my load test simulate real user interaction with the system besides just taking their word for it? Also, I've been reading up on how to create a load test scenario but I still don't know how to apply it to my project. Will someone from SmartBear be able to help me with that? 3) From http://smartbear.com/forums/forum/post/?mode=singleThread&thread=07c628a1-1344-4007-8542-b9f17162c15f, I thought that random think time would be introduced into TestComplete 8.1? How will that affect the reproducibility of the test? Is it better to use start delay if I want the results to be reproducible? Ramp Up StatisticsHi, (1) I was hoping that the ramp up feature would give us a graph to tell us the following: when we increase the number of concurrent user, how does the application behave. What I was expecting for the graph is something like: x = number of concurrent users (not total users), y = performance (kb/s). Even with v 7.5, it doesn't seem to do this. (2) Right now, the only way I can think of to have something similar to this is to create a bunch of load tests calling the same HTTP task, and assign each test different number of virtual users. Is there a way to achieve what I want in (1) with v 7.5? How about v 7.0?Re: Clarifications neededYour answers were very helpful, thank you.I'm still learning load testing, so I'm sorry for all of the basics that I need explaining. Thank you for being patient and for answering my questions. Re: Clarifications neededThank you for your last response, we've decided on a workaround implementation for this problem now. Re: Clarifications neededIf you can answer question 4 first, that would help me a lot. I need to know this to estimate the effort that I will have to spend to find a workaround for this problem.
