Load or Stress Testing Tool with URL Import Functionality - load-testing

Question

Can someone recommend a load testing tool which allows you to either:
a. replay an IIS (7) log(s) to simulate a real live site daily run;
b. import a CSV or equivalent list of URLS so we can achieve a similar thing as above but at a URL level;
c. .net API so I can create simple tests easily from my list of URLS is also a good way to go.
I do not really want to record my tests.
I think I can do B) with WAPT but need to create an XML file manually, not too much grief, but wondering if any tools cover these scenarios out the box.

Answer 1

Visual Studio Test Edition would require some code to parse the file into a suitable test run.
It is a great load testing solution.

Answer 2

Our load testing service lets you write a very simple script using JavaScript to pull data out of a CSV file and then fetch those URLs. For example, the following code would pluck 10 random URLs from the CSV file and fetch them as part of a single session:
var c = browserMob.openHttpClient();
var csv = browserMob.getCSV("urls.csv");
browserMob.beginTransaction();
for (var i = 0; i < 10; i++) {
browserMob.beginStep("Step 1");
var url = csv.random().get("url");
c.get(url);
browserMob.endStep();
}
browserMob.endTransaction();
The CSV file itself needs to be a normal CSV file with the first row containing a header named "url". This script would be run repeatedly for each virtual user participating in a load test.

We have support for so called 'uri-format' in our open-source tool called Yandex.Tank You simply put all your uris to a file, one uri -- one line, then specify headers in your load.ini like this:
[phantom]
address=example.org
rps_schedule=line(1, 1600, 2m)
headers = [Host: mts-maps.yandex.ru]
[Connection: close] [Bloody: yes]
ammo_file = ammo.uri
ammo.uri:
/
/index.html
/1/example.html
/2/example.html
