javascript - rxjs/redux observable Actions dispatched in the wrong order when running multiple tests -

i'm writing tests redux observable epics jasmine. when running 1 of tests "alone" (with fit(...)) test passes, when running in combination test (with it(...)) fails because actions dispatched in wrong order. appreciated!

there few epics i'm not going post them unless necessary.

this (kind of) test file:

const epicmiddleware = createepicmiddleware(combinedepics) const mockstore = configuremockstore([epicmiddleware])  describe('my test', () => {   let store    beforeeach(() => {     store = mockstore(...)     jasmine.ajax.install()   })    aftereach(() => {     jasmine.ajax.uninstall()     epicmiddleware.replaceepic(combinedepics)   })    // test 1 passes   it("test 1", () => {     jasmine.ajax.stubrequest("url-1").andreturn({       status: 200,       responsetext: json.stringify({ ... })     })      store.dispatch(initializepage())      expect(store.getactions()).toequal([       { type: initialize_page },       { type: my_action1 },       { type: initialized_page }     ])   })    // test 2 passes `fit` not `it`    it("test 2", () => {     jasmine.ajax.stubrequest("url-2").andreturn({       status: 200,       responsetext: json.stringify({ ... })     })      store.dispatch(initializepage())      expect(store.getactions()).toequal([       { type: initialize_page },       { type: my_action2 },       { type: initialized_page }     ])     /**      * `fit` actions come in order [initialize_page, my_action2, initialized_page]      * `it` actions come in order [initialize_page, initialized_page, my_action2]      */   }) }) 

turns out works if create epicmidleware in beforeeach instead of using epicmiddleware.replace(combinedepics). so:

describe('my test', () => {   let store   let epicmiddleware   let mockstore    beforeeach(() => {     epicmiddleware = createepicmiddleware(combinedepics)     mockstore = configuremockstore([epicmiddleware])     store = mockstore(...)     jasmine.ajax.install()   })    aftereach(() => {     jasmine.ajax.uninstall()   })    ...
