QUESTION
I got a problem like below: Compare 2 errors when writing unit test
...ANSWER
Answered 2021-Apr-29 at 15:32Depending on how you write your tests, you may depend on reflect.DeepEqual()
and ignore the linter warning ;
the drawback is : you start depending on the inner structure of the errors you return.
In the testing code I read, and the testing code we write, we use one of the following patterns :
- most of the time, we just compare the error to
nil
; - in some cases our functions return predefined error values, and we test for these specific values :
QUESTION
I have this helper function in my app that tells me the changes of newData
when compared to oldData
.
How can I refactor my getChanges function to make the test below pass? I thought I may need to make this function recursive since it executes itself from within itself, but I am not totally sure how to implement that.
It looks like this:

helper function:

rather than getChanges
):
QUESTION
I am trying to write an unbounded ping pipeline that takes output from a ping command and parses it to determine some statistics about the RTT (avg/min/max) and for now, just print the results.
I have already written an unbounded ping source that outputs each line as it comes in. The results are windowed every second for every 5 seconds of pings. The windowed data is fed to a Combine.globally
call to statefully process the string outputs. The problem is that the accumulators are never merged and the output is never extracted. This means that the pipeline never continues past this point. What am I doing wrong here?
ANSWER
Answered 2021-Mar-19 at 21:54One thing I notice in your code is that advance()
always returns True
. The watermark only advances on bundle completion, and I think it's runner-dependent whether a runner will ever complete a bundle if advance
ever never returns False
. You could try returning False
after a bounded amount of time/number of pings.
You could also consider re-writing this as an SDF.

I am new to Sinon, but I have looked around for a while trying to find an answer for this question..
I have a function I need to test, it returns a promise to call another function will callback.. Below is the function that I need to write test case for:
...ANSWER
Answered 2021-Mar-19 at 05:28The stubbed implementation by .callFake()
is not correct. The bookService.InfoRequest()
method accepts a callback parameter, the res
is passed to this callback. So you need to provide a stubbed implementation with this callback
function and pass your fake error.
E.g.
bookService.js

QUESTION
In the process of upgrading to ASP.NET Core 5, we have encountered a situation where we need to serialize and return a Json.NET JObject
(returned by some legacy code we can't yet change) using System.Text.Json
. How can this be done in a reasonably efficient manner, without re-serializing and re-parsing the JSON to a JsonDocument
or reverting back to Json.NET completely via AddNewtonsoftJson()
?
Specifically, say we have the following legacy data model:
...ANSWER
Answered 2020-Dec-21 at 00:09It is necessary to create a custom JsonConverterFactory
to serialize a Json.NET JToken
hierarchy to JSON using System.Text.Json
.
Since the question seeks to avoid re-serializing the entire JObject
to JSON just to parse it again using System.Text.Json
, the following converter descends the token hierarchy recursively writing each individual value out to the Utf8JsonWriter
:
QUESTION
I'm setting up unit testing using marklogic-unit-test and one thing I'd like to do is check a given document has a particular permission. However, when I test my permission against a Sequence of permissions, I get an XDMP-NONMIXEDCOMPLEXCONT
error. I assume this has to do with the fact that permissions are complex objects and not something like a simple string, because this works with collections.
ANSWER
Answered 2020-Nov-10 at 16:05The test.assertAtLeastOneEqual()
function expects atomic values (item()
signature). The only test helper function that can handle elements is test.assertEqualXml()
, but that looks for exact matches. I think your best bet is to stringify the permissions. Something like this:

Answered 2020-Nov-08 at 22:27Having a look through the source code of DeepEqual, the library allows for custom comparisons via the IComparison
interface. With that, I simulated the models that you require:

The problem itself is more complex than this but I'll try to explain in a simple way.
I have an object (it could be a different object, lets say a car o user or whatever).
...ANSWER
Answered 2020-Oct-28 at 17:44I'm going to preserve your implementation as much as possible, even though there might be some improvements there that someone would suggest. I'm primarily taking this question as "how can I tell the TypeScript compiler what getValues()
is doing?".
First, we need to represent what comes out when you deeply index into a type T
with a dotted keypath K
. This is only going to be possible in TypeScript 4.1 and later, since the following implementation relies both on template literal types as implemented in microsoft/TypeScript#40336, and recursive conditional types as implemented in microsoft/TypeScript#40002:
