Jasmine halts after 2nd call to the same async mock function in test function

I suspect Jasmine halts after running an async mocked function 2nd time in the same function, but I cant seem to find the reason or the correct workaround.

The getDialogAnswer is a jquery dialog wrapped in a promise and async await function. This is an implementaiton of "delete" + "are you sure" dialog boxes. Everything works as expected in the running application.

the 2 calls

let optiontext = 'Delete project from plan?'
let deleteProject = await getDialogAnswer(title, optiontext, choices, defaultvalue)
...
optiontext = 'REALLY delete project from plan???<br>There is no going back'
deleteProject =  await getDialogAnswer(title, optiontext, choices, defaultvalue)

The mock function

const getDialogAnswer = jasmine.createSpy('Mock_getDialogAnswer').and.returnValues('yes','yes');

The test function is created with async

it("should delete on yes + yes", async () => {

This passes

expect(getDialogAnswer).toHaveBeenCalledTimes(2)

but following 4 of this type fails - says called 0 times.

expect(mainPart.clearSelected).toHaveBeenCalledTimes(1)

The last I check is

expect(unsaved_changes).toBe(true);

which reports "Expected null to be true." But a console output writes correct true, so I know the function finished correctly.

The test is running in Jasmine HTML standalon Specrunner. I have tested with both 4.6,4.6 and 5.0Beta.

If I change the second call

deleteProject =  await getDialogAnswer(title, optiontext, choices, defaultvalue)

to

deleteProject =  'yes'

getDialogAnswer is of course only run once, but the rest of the expectaions pass!

And if I just remove the await of the second call to be like this

deleteProject =  getDialogAnswer(title, optiontext, choices, defaultvalue)

It all passes test - but then I cannot delete in the real application! Here the delete is not carried through.

I have gone through all I could find on async and spyes in the doc https://jasmine.github.io/index.html, and tried the method

const getDialogAnswer = jasmine.createSpy('Mock_getDialogAnswer').and.returnValues(
    Promise.resolve('yes'),Promise.resolve('yes'));

With same result

I have searched here, but mainly found how to setup test functions. I have a suspecion that I may have setup my mock fucntion incorrect or that Jasmine maybe has a flaw here. But I cant find any documentaion or other thread that shed some light on this. This might be a lead, but it seems to me that I am already doing it right. How to test async function with spyOn? Or am I missing something tiny but essential?

The number of nodes and edges I calculated manually and by a method provided by networkx library dont match

I am trying to analyse a graph using networkx library in Python. I have implemented a function that returns the nodes and edges of that graph. After that I counted the number of nodes and edges by implementing the len() function for nodes and edges, which gave me 17 for both nodes and edges. However, when I used the method graph.number_of_nodes() of networkx library it gave me 53. My code: import pandas as pd import networkx as nx import matplotlib.pyplot as plt header_list = ["a","b","w"] E =pd.read_csv("aves-barn-swallow-contact-network.edges",sep=" ",header= None,names=header_list) # print(E.head()) # prints first few rows of the csv file G = nx.from_pandas_edgelist(E,"a","b",["w"]) nx.draw(G) plt.show() class GraphAnalyse: #finding nodes and edges def nodeEdge(self,Graph): nodes = Graph.nodes() edges = Graph.edges() ...
