Jest coverage in redux reducer - object destruction not covered - ecmascript-6

Question

I have the following issue with Jest:
I have this reducer:
[REMOVE_FILTER]: (state: FiltersState, action: Action<string>): FiltersState => {
const { [action.payload!]: deleted, ...activeFilters } = state.activeFilters;
return { ...state, activeFilters, createFilterSelection: undefined, filterCreateOpen: false };
}
When I am trying to test it, it says that I do not have coverage for
...activeFilters } = state.activeFilters;
Here is my test:
test(REMOVE_FILTER, () => {
const action: IAction<string> = {
type: REMOVE_FILTER,
payload: "subprovider"
};
expect(
testReducer({ reducer, state, action })
).toEqual({
...state,
activeFilters: { name: null, branded: null },
createFilterSelection: undefined,
filterCreateOpen: false
});
});
Can someone suggest what I am doing wrong?
I am using:
Jest 23.6.0
Typescript 3.4.0
Redux 4.0.0
React-Redux: 6.0.0
Redux Actions: 2.6.1
Thank you!
P.S: Here is the Jest config:
{
"coverageThreshold": {
"global": {
"branches": 100,
"functions": 100,
"lines": 100,
"statements": 100
}
},
"globals": {
"window": true,
"document": true
},
"transform": {
".(ts|tsx)": "<rootDir>/node_modules/ts-jest/preprocessor.js"
},
"testRegex": "(/__test__/.*)\\.test\\.(ts|tsx)$",
"notify": true,
"collectCoverageFrom": [
"**/*.{ts,tsx}"
],
"coveragePathIgnorePatterns": [
"(/__e2e__/.*)",
"(/__specs__/.*)",
"(/__test__/.*)",
"(/interfaces/.*)",
"(index.ts)",
"(src/server/app.ts)",
"(src/server/config.ts)",
"(/mock/.*)",
"(data/mock.ts)",
"(automapperConfiguration.ts)",
"(src/app/store/store.ts)",
"(src/app/containers/brand-configuration/.*)"
],
"moduleFileExtensions": [
"ts",
"tsx",
"js",
"json"
],
"setupTestFrameworkScriptFile": "<rootDir>/jestSetup.js",
"testURL": "http://localhost/"
}
The above TS code gets transpilled to:
[REMOVE_FILTER]: (state, action) => {
const _a = state.activeFilters, _b = action.payload, deleted = _a[_b], activeFilters = __rest(_a, [typeof _b === "symbol" ? _b : _b + ""]);
return Object.assign({}, state, { activeFilters, createFilterSelection: undefined, filterCreateOpen: false });
}
