I am getting the following when trying out the assertions, any idea what I could be missing out here (using 2.0.0-M3a):

[https://github.com/softmentor/gatling-examples/blob/master/gatling-custom-protocol-demo/src/test/scala/custom/protocol/test/TestCustomProtocolSimulation.scala](https://github.com/softmentor/gatling-examples/blob/master/gatling-custom-protocol-demo/src/test/scala/custom/protocol/test/TestCustomProtocolSimulation.scala)

I have done import and assertThat (as per the documentation)  
_import assertions.\__

…

_assertThat(_  
_global.responseTime.max.lessThan(50),_  
_global.successfulRequest.percent.greaterThan(95))_

You can run the whole example here:  
[https://github.com/softmentor/gatling-examples](https://github.com/softmentor/gatling-examples)

Exception when I run: _mvn clean test_

Hi,

This changed in M3: [https://github.com/excilys/gatling/wiki/Gatling-2#wiki-assertions](https://github.com/excilys/gatling/wiki/Gatling-2#wiki-assertions)

Note that we have a test class that’s not intended to run, but just to check that everything compiles fine: [https://github.com/excilys/gatling/blob/2.0.0-M3a/gatling-app/src/test/scala/io/gatling/app/test/CompileTest.scala#L205](https://github.com/excilys/gatling/blob/2.0.0-M3a/gatling-app/src/test/scala/io/gatling/app/test/CompileTest.scala#L205)

Cheers,

Stéphane

Perfect, it worked.  
I fixed my example also.
