Fdbserver test fails with assertion error


I’m new to foundationdb and I’m trying to run some basic tests. I’m hitting assertion error when I tried to run InventoryTestSomeWrites. I have verified that foundationdb service is running ok and there are no errors.

Can someone please let me know what is the reason for getting assertion error and how do I fix it?

The tests/default.txt just has one test InventoryTestSomeWrites as shown below.




fdbserver -r test

startingConfiguration: start

Run test:InventoryTestSomeWrites start

setting up test (InventoryTestSomeWrites)…

Test received trigger for setup…

running test (InventoryTestSomeWrites)…

The recommended way to run a suite of simulation tests locally is to invoke ctest in your build directory.

Thank you for the reply. I’m running into some error when I tried to run the test through TestRunner.py. Could you please check below and let me know how to run this correctly.

Is there any documentation with steps on how to run these tests? That would be really helpful.

These are the two ctest files I see in my source and build directories:


[nkss@buildbox2 TestRunner]$ pwd
local_cluster.py logs TestDirectory.py TestDirectory.pyc testfile.txt TestRunner.py tmp_cluster.py

[nkss@buildbox2 TestRunner]$ ./TestRunner.py -b /home/nkss/git/fdb/build -s /home/nkss/git/fdb/foundationdb -t simulation testfile.txt

Traceback (most recent call last):
File “./TestRunner.py”, line 444, in
res = run_simulation_test(basedir, args)
File “./TestRunner.py”, line 331, in run_simulation_test
‘test_{}’.format(options.name.replace(’/’, ‘_’)))
AttributeError: ‘NoneType’ object has no attribute 'replace

I figured out what I was missing. Now, I’m able to run the test via ctest but I’m getting simfdb not found error. How do I create simdb? Could you please get to back to me.
