Hi Sara! It is a really hard assignment, you have to reverse engineer requirements from the code and translate them to tests... but usually creating of tests should guide a design of the code: http://www.growing-object-oriented-software.com/
For small projects (like here https://github.com/plokhotnyuk/calculator ) end to end tests can check all requirements, but when the system grows to layers of subsystems unit tests will help a lot.
@saraervik it is pretty important to explore the test space by generating random data. There is https://github.com/google/gofuzz that can generate data. But there are two missing requirements: 1. generate data for interface{} or any interface. 2. generate the type structure randomly. For simple library like json parser, there are limited interaction combinations, most of the time it is just marshal => unmarshal. So random data is sufficient to test it. For more complex library, there are lots of api, lots of interaction sequence, randomize the action list itself is worth considering.
Hi! How to read values from reader instead of bytes? (go)
Here is a small example: https://pastebin.com/mKdqEsvv
If I pass []byte (via BorrowIterator or ResetBytes) - everything is working. But if I use reader - it hangs on WhatIsNext.
Is this a bug? Or I'm doing something wrong?

Hello there :D
I am using JsonIter on a small java project where i found a problem related with enconding.
For example:
I get an response from a rest API (UTF-8), in which, inside exist something like { "name" : "RÉM", "id" : 85 }
If i do JsonIterator.deserialize(String).get("name").toString() the value that i receive its different from original.
But if i use JsonIterator.deserialize(String).toString() the value its equal to original.
Its needed some pre-configuration on JsonIterator?
Thanks in advance.
Regards

can i use the jsoniter to parse the data like
{ signedTransaction: '120003240000001268400000000000000C732102C05E14297AF16E26C8B6791C2D3E9B2BAE3BE3B1799C5D19B3A142B8B68FBFB274473045022100E4206AE8294A39E750D7563AA53F4781298887B60735079392F36EAC9E5A516402203EF22B800A17709430F2FFBE7B0AF09C139C506922DBADEE53550453C10AC44C770A726970706C652E636F6D8114AF1E8A7778C7A043C5927AC851F8571CCAC27A0E', id: '4452B677BEA23242B40EB9B317150E74484005F6035AD5238324C9BADD859647' }
?
I have tried to ,but it didn't work
Oops. I'm wondering how to perform custom field encoding with Jsoniter, as I need to put directives in the json fields, e.g. if I have the json tag(Golang) "name" I need to encode it as "name@en". Does the API perform such changes, or will I have to fork it? Thanks :)
extra.SetNamingStrategy(extra.LowerCaseWithUnderscores)
err := jsoniter.NewEncoder(into).Encode(&from)
if err != nil {
return errors.Wrap(err, errEncoding)
}
return nil
@lfaoro I can help with Java (https://github.com/json-iterator/java) or Scala (https://github.com/plokhotnyuk/jsoniter-scala) versions only
In Scala, name mapping is set in compile time only by name mapping function of codec derivation configuration (for snake_case enforcing, etc.) or by
@named annotation (usually for exceptional cases)
Or may be I should use some another library ?
This is in Java.
@taowen I submitted a PR to add the ability to specify a custom map key sorting function, to allow for, for example, certain map keys to always appear at the top of the serialized map string. Builds are passing, here is the PR and the issue. Thanks!
with this as benchmark code
func BenchmarkMarshallStd(b *testing.B) {
j := CalendarOutput{}
_ = json.Unmarshal([]byte(outputSmallJsonString), &j)
b.ResetTimer()
for i := 0; i < b.N; i++ {
_, _ = json.Marshal(j)
}
}
func BenchmarkMarshallIter(b *testing.B) {
j := CalendarOutput{}
_ = json.Unmarshal([]byte(outputSmallJsonString), &j)
b.ResetTimer()
for i := 0; i < b.N; i++ {
_, _ = jsoniter.ConfigCompatibleWithStandardLibrary.Marshal(j)
}
}I get these results

i'm here to ask if you could please retag the
json-iterator/go#412
v1.1.8 release? it was mistakenly tagged as 1.1.8 (without the v).json-iterator/go#412
go get github.com/json-iterator/go@v1.1.8 fails
that's it. thanks very much!
