How can i test an observable that has pipe and map? - javascript

I'm assigning values to this variables inside ngOnInit:
this.simStatsList$ = this.sideMenuService.getSimStatsList();
this.currentStation$ = this.simStatsList$.pipe(
map(station => station.find((station: ISimStats) => station.stationName === this.authService.userStation)),
) as Observable<ISimStats>;
This is my test:
it('should select userStation as currentStation', () => {
component.currentStation$.subscribe((response) => {
expect(response).toEqual(
{ stationName: 'test', stats: { open: 0, down: 0, preflight: 0 } }
);
});
});
It passes but is not covering the map function from rxjs. Also im providing sideMenuService and AuthService as mocked values and this is my mock. I'm missing something but i don't know what is it.
export const mockSideMenuService = {
getSimStatsList: () =>
of([
{ stationName: 'test', stats: { open: 0, down: 0, preflight: 0 } },
{ stationName: 'test1', stats: { open: 1, down: 1, preflight: 1 } }
] as ISimStats[])
}
export const mockAuthService = {
userStation: 'test'
}
Could you help me to cover the whole code?

After #will alexander comment i did some change and it worked:
First, pass the function to the sideMenuService and recieve needed data as parameters:
side-menu.service.ts
getCurrentSimStats(
simStatsList$: Observable<ISimStats[]>,
currentStation: string): Observable<ISimStats> {
return simStatsList$.pipe(
map((station) => station.find((station: ISimStats) => station.stationName === currentStation))) as Observable<ISimStats>;
}
Then my component test coverage passed as 100% but the sideMenuService wasn't so i wrote this small test on service spec file:
side-menu.service.spec.ts
it('should getCurrentStation', () =>{
service.getCurrentSimStats(of(mockSideMenuService.mockSimStatsResponse), 'test').subscribe((res) => {
expect(res).toEqual(mockSideMenuService.mockCurrentSimStatsResponse);
});
})
After this, everything worked and tests are passing!

Using XState, how can I access name of current state in an action?

I'm playing around learning XState and wanted to include an action in a machine that would just log the current state to console.
Defining a simple example machine like so, how would I go about this? Also note the questions in the comments in the code.
import { createMachine, interpret } from "xstate"
const sm = createMachine({
initial: 'foo',
states: {
foo: {
entry: 'logState', // Can I only reference an action by string?
// Or can I add arguments here somehow?
on: {
TOGGLE: {target: 'bar'}
}
},
bar: {
entry: 'logState',
on: {
TOGGLE: {target: 'foo'}
}
}
}
},
{
actions: {
logState(/* What arguments can go here? */) => {
// What do I do here?
}
}
});
I know that actions are called with context and event as arguments but I don't see a way to get the current state from either of those. Am I missing something here?
For a simple use case like yours, you could try recording the state on transition.
let currentState;
const service = interpret(machine).onTransition(state => {
if (state.value != currentState) {
// TODO: terminate timer if any and start a new one
currentState = state.value;
}
});
Then use the value in your actions.
See more here: https://github.com/statelyai/xstate/discussions/1294
Actions receive three arguments - context, event and meta. meta have property state, which is current state.
import { createMachine } from "xstate";
let metaDemo = createMachine(
{
id: "meta-demo",
initial: "ping",
states: {
ping: {
entry: ["logStateValues"],
after: { TIMEOUT: "pong" },
},
pong: {
entry: ["logStateValues"],
after: { TIMEOUT: "ping" },
},
},
},
{
delays: {
TIMEOUT: 3000,
},
actions: {
logStateValues(ctx, event, meta) {
if (meta.state.matches("ping")) {
console.log("It's PING!");
} else if (meta.state.matches("pong")) {
console.log("And now it's PONG");
} else {
console.log(
`This is not supposed to happen. State is: ${meta.state
.toStrings()
.join(".")}`
);
}
},
},
}
);

How to apply iterations condition for function in K6

I want to execute logout function for one time and dropDown function for multiple iterations. Which changes shoul I need in below code.
executors: {
logout: {
type: 'per-vu-iterations',
exec: 'logout',
vus: 1,
iterations: 1,
startTime: '30s',
maxDuration: '1m',
tags: { my_tag: 'LOGOUT'},
},
}};
export function logout() {
group('Logout API', () => {
loginFunctions.logout_api();
})
}
export function dropDown() {
group('Drop Down API', () => {
loginFunctions.dropDown_api();
})
}
export default function () {
logout();
dropDown();
}
Also without default function it's not working. getting executor default: function 'default' not found in exports this error
Not sure where you saw executors, that was the old name of the option, before #1007 was merged and released. The new and correct name is scenarios: https://k6.io/docs/using-k6/scenarios
So, to answer your question, the code should look somewhat like this:
import http from 'k6/http';
import { sleep } from 'k6';
export let options = {
scenarios: {
logout: {
executor: 'per-vu-iterations',
exec: 'logout',
vus: 1, iterations: 1,
maxDuration: '1m',
tags: { my_tag: 'LOGOUT' },
},
dropDown: {
executor: 'per-vu-iterations',
exec: 'dropDown',
vus: 10, iterations: 10, // or whatever
maxDuration: '1m',
tags: { my_tag: 'LOGOUT' },
},
}
};
export function logout() {
console.log("logout()");
sleep(1);
// ...
}
export function dropDown() {
console.log("dropDown()");
sleep(1);
// ...
}
Though, depending on your use case, the best place for the logout() code might actually be in the teardown() lifecycle function? See https://k6.io/docs/using-k6/test-life-cycle for more details

How to avoid [Vue warn] for custom directive?

I created a custom directive and it's working good, but when I run the mocha test for the component where I use this custom directive I receive this warning message [Vue warn]: Failed to resolve directive: scroll-text, tell me please how to fix that
test file:
import { shallowMount } from "#vue/test-utils"
import { scrollText } from "z-common/services"
import ZSourcesList from "./ZSourcesList"
Vue.use(scrollText)
const stubs = [
"z-text-field",
"v-progress-circular",
"v-icon",
"z-btn"
]
describe("ZSourcesList.vue", () => {
const sources = []
for (let i = 0; i < 20; i++) {
sources.push({
field: "source",
// format numbers to get 2 diggit number with leading zero 1 -> 01
value: `cluster-${i.toLocaleString('en-US', { minimumIntegerDigits: 2, useGrouping: false })}`,
__typename: "SuggestV2Result"
})
}
it("displays 'No matching sources found' if there are no sources", () => {
const wrapper = shallowMount(ZSourcesList, {
mocks: {
$apollo: {
queries: {
suggestions: {
loading: false,
},
},
},
},
stubs,
sync: false,
data() {
return {
suggestions: [],
}
},
})
expect(wrapper.find(".notification .z-note")).to.exist
})
})
Try registering your custom directive on a local vue instance and then mounting to that local vue instance.
import { shallowMount, createLocalVue } from "#vue/test-utils"
import { scrollText } from "z-common/services"
import ZSourcesList from "./ZSourcesList"
const localVue = createLocalVue()
localVue.use(scrollText) // Register the plugin to local vue
const stubs = [
"z-text-field",
"v-progress-circular",
"v-icon",
"z-btn"
]
describe("ZSourcesList.vue", () => {
const sources = []
for (let i = 0; i < 20; i++) {
sources.push({
field: "source",
// format numbers to get 2 diggit number with leading zero 1 -> 01
value: `cluster-${i.toLocaleString('en-US', { minimumIntegerDigits: 2, useGrouping: false })}`,
__typename: "SuggestV2Result"
})
}
it("displays 'No matching sources found' if there are no sources", () => {
const wrapper = shallowMount(ZSourcesList, {
mocks: {
$apollo: {
queries: {
suggestions: {
loading: false,
},
},
},
},
localVue, // Mount this component to localVue
stubs,
sync: false,
data() {
return {
suggestions: [],
}
},
})
expect(wrapper.find(".notification .z-note")).to.exist
})
})
Using a local vue instance instead of the global in test cases will also prevent polluting the global vue instance and help to prevent side effects in other test cases.

TypeError: Cannot read property 'caption' of undefined

Trying to test if the following function gets called correctly.
Here is the function, using Jest and Enzyme for React Js:
changeCurrentColumn = (e) => {
{
if(e.target.value !== 'default')
{
const id = e.target.value
const name = this.props.defaultData[e.target.value].caption
this.props.setCurrentColumn({ name, id })
}
}
}
Here is the test:
it('changeCurrentColumn function test', () => {
wrapper.setProps({
defaultData:[{
caption:"test"
},],
}),
wrapper.update();
The error is pointing to ({target:'test'})) :
expect(wrapper.instance().changeCurrentColumn({target:'test'})).toBeDefined();
})
What can I add after 'test' in order to read the property of 'caption'?
Thanks.
You can change the type of the defaultData to object something like this.
it('changeCurrentColumn function test', () => {
const event = {
target: {
value: "caption"
}
}
wrapper.setProps({
defaultData:{
caption:"test"
},
}),
wrapper.update();
expect(wrapper.instance().changeCurrentColumn(event)).toBeDefined()
});
or pass value as 0 to get rest from the existing defaultData.
it('changeCurrentColumn function test', () => {
const event = {
target: {
value: 0
}
}
wrapper.setProps({
defaultData:[{
caption:"test"
}],
}),
wrapper.update();
expect(wrapper.instance().changeCurrentColumn(event)).toBeDefined()
});

Jasmine test with selecting items from list

I have an angular application and I need to do some unit testing on some methods with Jasmine. IN this case I do a unit test on a select list. So that the select list will not be empty.
The method looks like this:
createStatusOptions(listValueoptions: OptionModel[], resources: any): OptionModel[] {
const processStatusOptions = listValueoptions.map(listValueOption => {
listValueOption.value = `${caseStatusEnum.inProgress}_${listValueOption.value}`;
listValueOption.selected = true;
return listValueOption;
});
const caseStatusEnumKeys = Object.keys(caseStatusEnum).filter(key => !isNaN(Number(key)));
const enumOptions = this.optionService.createOptions(
new ConfigOptionModel({ source: caseStatusEnumKeys, resources, resourcesModel: enumResourcesModel, isCustomEnum: true, }));
return [
this.getEnumOption(enumOptions, caseStatusEnum.submitted, true),
...processStatusOptions,
this.getEnumOption(enumOptions, caseStatusEnum.closed),
];
}
private getEnumOption(options: OptionModel[], enumType, isSelected = false): OptionModel {
const option = options.filter(enumOption => enumOption.value === `${enumType}`)[0];
option.selected = isSelected;
return option;
}
And I have the unit test like this:
it('should create status options when there ar list value options are provided', () => {
optionService.options = [
{
value: caseStatusEnum.submitted.toString(),
},
{
value: caseStatusEnum.inProgress.toString(),
},
{
value: caseStatusEnum.closed.toString(),
},
] as OptionModel[];
// tslint:disable-next-line:max-line-length
const result = service.createStatusOptions(optionService.options, [[103], [104], [105] ]);
console.log(result);
expect(result.length).toBe(2);
expect(result).toEqual([{ value: '103', selected: true }, { value: '105', selected: false }]);
});
But I get an error like this:

Based on what you showed so far, my guess is that the options parameter passed to getEnumOption() is undefined, which is causing the error you see. A quick console.log(options) within getEnumOption() would verify this.
If your code is working fine otherwise, but only failing in the test then I would make a second guess that you haven't properly mocked/spiedOn this.optionService.createOptions() since it sets up the options parameter that is potentially undefined. That would have been done earlier in the .spec file - if you post the whole file then that would help others who read your question to determine if this is the case.
Update with Stackblitz
I put all your code into a Stackblitz to test it. There was a lot of code I didn't have access to that I just guessed at the functionality of. However, I did discover a few things.
First, when you are testing you appear to be using the same variable both for the mock of the return expected by this.optionService.createOptions() as well as in the call to service.createStatusOptions() - which is likely not what you want to do.
Here is the code snippet I am talking about:
optionService.options = [
{
value: caseStatusEnum.submitted.toString(),
},
{
value: caseStatusEnum.inProgress.toString(),
},
{
value: caseStatusEnum.closed.toString(),
},
] as OptionModel[];
// tslint:disable-next-line:max-line-length
const result = service.createStatusOptions(optionService.options, [[103], [104], [105] ]);
When I called it this way in the Stackblitz I ran into a mutability issue - you are changing the data within the members of the objects inside the array, which will change it whereever that variable is accessed. To overcome this in the Stackblitz I made two copies of the data, one to use in the mock returnValue and another completely separate array of objects for the call to service.createStatusOptions(). Also, I am not familiar with the way you are mocking your service call, so I replaced it with a simple Jasmine spy in the Stackblitz.
Feel free to have a look at what I produced. Perhaps it will be helpful.
