for university purposes i'm trying to extend evosuite. before i'm tryng to run it first with a different GA, without success.
I'm using evosuite 1.2.1 on ubuntu 12.0.4 and after compile it with maven, following the tutorial on the website, i try to run evosuite having changed some parameters like GA.
Reading the documentation, the command line i wrote is this:
$EvoSuite -class tutorial.Stack -projectCP Tutorial_Stack/target/classes/ -Dalgorithm=CELLULAR_GAw
here "EvoSuite" is the export where i declare the command
java -jar path_evosuite-master.jar
the result is this:
EvoSuite 1.2.1-SNAPSHOT
Going to generate test cases for class: tutorial.Stack
Starting Client-0

if I have not misunderstood, the system runs using the GA chosen, but fails to generate tests.
can anyone help me to understand how to use it with different ga successfully?
