"When I run tests, they passed. But when I want to submit, it tells me that basicTests failed."

I have the same problem.
My output:

basicTests(XbonacciTest)
10
randomTests(XbonacciTest)
...
Test Passed

1 Passed
1 Failed
0 Errors

Java.

Java.
Input data is from "Your test cases" field: {0,1},10; {1,1},10; {0,0,0,0,1},10; {1,0,0,0,0,0,1},10.

I press "Submit" and get it:

basicTests(XbonacciTest)
10
randomTests(XbonacciTest)
...
Test Passed

1 Passed
1 Failed
0 Errors

The same problem, basicTests failed with errorcode "10". In IntellijIDEA my solution works good.
What does it mean?
