+#### Environment variables
+
+The `v4` unit tests make use of the below, optional environment variables to control their rigour and runtime.
+
+
+| Environment variable  | Default | Description |
+| -------- | ------- | ------- |
+| `TEST_NUM_QUBITS_IN_QUREG` | `6` | The number of qubits in the Qureg(s) undergoing unit testing. In addition to operation upon larger Quregs being exponentially slower, beware that more qubits permit more variations and permutations of input parameters like target qubits, factorially increasing the number of tests per operation. |

Set to `0` (default) to test all permutations, or to a positive integer (e.g. `50`) to accelerate the unit tests. See more info [here](https://quest-kit.github.io/QuEST/group__testutilsconfig.html#gac5adcc10bd26c56f20344f5ae3d9ba41). |
+| `TEST_MAX_NUM_SUPEROP_TARGETS` | `4` | The maximum number of superoperator targets for which to unit test functions `mixKrausMap()` and `mixSuperOp()`. These are computationally equivalent to simulating unitaries with double the number of targets upon a density matrix. Set to `0` to test all sizes which is likely prohibitively slow, or to a positive integer (e.g. the default of `4`) to accelerate the unit tests. |
