Moxios Requests State Not Cleared In Between Tests - mocha.js

Question

My specs are behaving weirdly in that when I run the tests alone, they pass. However, when I run the test suite all together, the failure tests still continue to use the success axios mock instead of using the correct failing http axios mock. This results in my tests failing. Am I missing something for isolating the 2 mocks from each other in the different portions of code?
jobactions.js
export const loadUnassignedJobs = (job_type) => {
if (!['unscheduled', 'overdue'].includes(job_type)) {
throw 'Job Type must be "unscheduled" or "overdue".';
}
return (dispatch) => {
dispatch({type: JobActionTypes.LOAD_UNASSIGNED_JOBS_STARTED, job_type });
return axios.get(defaults.baseapi_uri + 'jobs/' + job_type)
.then(function (response) {
dispatch(updateUnassignedJobs(response.data.jobs));
// handle success
})
.catch(function (error) {
// handle error
dispatch({ type: JobActionTypes.LOAD_UNASSIGNED_JOBS_FAILURE, error });
})
.then(function () {
// always executed
});
}
};
export const updateUnassignedJobs = (unassigned_jobs) => {
let unassigned_job_ids = [];
let jobs = {};
for (let job of unassigned_jobs) {
unassigned_job_ids.push(job.id);
jobs[job.id]=job;
}
return({
type: JobActionTypes.LOAD_UNASSIGNED_JOBS_SUCCESS,
jobs,
unassigned_job_ids,
});
};

Found the issue!
The it() blocks for the success case were not using the done callback causing the afterEach() moxios.uninstall() to be called prematurely and not resetting the requests after the call was complete. Fixing this, and now all the tests pass.
