+# Debugging Tests
+
+The easiest way to debug tests while writing them is to run the test with the `--traces` flag. This will output the traces of the test, which can be used to understand the behavior of the test and the client.
+
+```bash
+fill 'tests/frontier/opcodes/test_dup.py::test_dup[fork_Byzantium-state_test-DUP1]' --traces
+```
+
+Depending on the test failure type, a list of relevant traces will be printed.
+
+For example, if the test fails because an expected storage key was not set (`Storage.KeyValueMismatch`), the output will show EVM traces where the storage key was set, or the executing contract returned with error.

+
+In this example, the test failed because the storage key `0x0` was not set. The traces show that the storage key was indeed set to `0x10`, but later the contract ran out of gas.
