I am using ScalarDB. It provides ACID capabilities over Cassandra. - https://scalar-labs.github.io/scalardb/javadoc/
ScalarDB is Java based and I am using it in Scala code
The way to insert a value in Cassandra using Scalardb is to call Put method. Eg.
def add() = {
val putAnswer: Put = new Put(pAnswerKey)
.forNamespace(keyspaceName)
.forTable(tablename)
.withCondition(mutationCondition)
.withValue(new TextValue("answer_id", answer.answer_id.get.toString))
.withValue(new TextValue("image", convertImageToString(imageData)))
.withValue(new TextValue("answer", convertAnswersFromModelToString(answer.answer)))
.withValue(new BigIntValue("creation_year", answer.creationYear.getOrElse(0)))
.withValue(new BigIntValue("creation_month", answer.creationMonth.getOrElse(0)))
.withValue(new TextValue("notes", answer.notes.getOrElse("")))
logger.trace(s"putting answer ${putAnswer}")
transaction.put(putAnswer)
....
}
I want to unit test the add method by capturing the argument passed to put. I am stuck at a point where I don't know how to get the Value passed to put. How do I type cast to required values?
repository.add(repoTestEnv.mockDistributedTransaction,repoTestEnv.answerTestEnv.answerOfAPracticeQuestion)
val argumentCaptor = ArgumentCaptor.forClassPut,Put
verify(repoTestEnv.mockDistributedTransaction,times(1)).put(argumentCaptor.capture())
val argumentsInvoked = argumentCaptor.getAllValues
argumentsInvoked.size mustBe 1
val argument = argumentsInvoked.get(0)
val values = argument.getValues //this is util.Map[String,Value[_]]
logger.trace(s"arguments were ${argument.getValues}") //this prints the following
{answer_id=TextValue{name=answer_id, value=Optional[11111111-1111-1111-1111-111111111111]}, image=TextValue{name=image, value=Optional[{"image":["image1binarydata","image2binarydata"]}]}, answer=TextValue{name=answer, value=Optional[{"answer":[{"filename":"c.js","answer":"some answer"}]}]}, creation_year=BigIntValue{name=creation_year, value=2019}, creation_month=BigIntValue{name=creation_month, value=12}, notes=TextValue{name=notes, value=Optional[some notes]}}
Problem - I don't know how to further pick each value and compare it.
As Value is an interface, I had to typecast it like follows.
val value = values.get("answer_id").asInstanceOf[TextValue]
value.getString.isPresent mustBe true
value.getString.get() mustBe "11111111-1111-1111-1111-111111111111"
Why don't you create an expected Put and verify with Mockito?

In Gatling, I am using feeders to pass the values of the coordinates in a request, below is the code. I want on each repeat a new value from the feeder to be picked up. I am get the following error --
/mapping/v2/: Failed to build request: No attribute named 'map 30 (100.0%) x' is defined
Could someone please advice how this can be achieved. thanks.
val mapfeeder = csv(fileName = "data/cordinates.csv").circular
object PDP {
val pdp = group("ABC_01_DetailsPage") {
exec(http("PropertyDetailsPage")
.get("/abc/property/detail.html?propertyId=12345&index=0&q=${address_json6}&qt=address&_qt=address&offset=1&sort=address&limit=20&view=property&mode=&radius=1.0Km&landuse=All")
.check(substring("Change in Median Price")))
}
.pause(duration = 1)
.feed(mapfeeder) //this works but only take the fist value and repeats it 30 times
.group("ABC_02_DetailsPage_MAP") {
repeat(30) {
feed(mapfeeder) // this one fails with the error mentioned in the post
exec(http("/mapping")
.get(uri22 + "?mapTypeId=1006&x=${mapx}&y=${mapy}&z=19&access_token=${maptoken}"))
}
val scn = scenario("RecordedSimulation")
.feed(SearchFeeder)
.exec(Homepage.homepage, Login.login, SearchLink.search, SearchEntry.searchentry, PDP.pdp, Logout.logout)
setUp(scn.inject(atOnceUsers(1))).protocols(httpProtocol)
You're missing a dot to attach your feed and the following exec, so only the result of the last instruction (the exec) is passed to the repeat method.
It should be:
repeat(30) {
feed(mapfeeder)
.exec(
http("/mapping") // <== HERE, DOT WAS MISSING
.get(uri22 + "?mapTypeId=1006&x=${mapx}&y=${mapy}&z=19&access_token=${maptoken}")
)
}
I am new to scala and gatling . I am trying to fetch values from feeder and post zip file to service . but ${extensionId} is not been updated with fetched value instead it remain as ${extensionId} . Could some one please help me know If I miss some thing here .
def installExtension() =
exec(http("template - Install Extension")
.post(url + "/v1/extensions")
.basicAuth("jack", "password")
.headers(namespaceHeader)
// using testUtils to get InputStream conte
.body(InputStreamBody(TestUtils.toStream(hashMap.get("${extensionId}").getOrElse(null))))
.check(status.is( 201)))
class extmgrSimulations extends Simulation {
val extensionIds = csv(s"${Configuration.dataDirectory}/extensionId.csv").circular
val extMgrScenerio = scenario("extensionMgr - Scenario")
.during(Configuration.duration) {
exitBlockOnFail(
group("load-test") {
exec(
pace(Configuration.paceFrom, Configuration.paceTo),
feed(extensionIds),feed(extensionIds)
randomSwitch(
50.00 -> group("Install and delete") {
exec(
extmgrChain.installExtension(),
extmgrChain.deleteExtension(),
)
},
50.00 -> extmgrChain.listExtension()
)
)
}
)
}
That can't work. Gatling EL (the ${} syntax in strings) doesn't magically work anywhere. This is explained in the documentation.
Warning
This Expression Language only works on String values being passed to Gatling DSL methods. Such Strings are parsed only once, when the Gatling simulation is being instantiated.
For example queryParam("latitude", session => "${latitude}") wouldn’t work because the parameter is not a String, but a function that returns a String.
Also, queryParam("latitude", "${latitude}".toInt) wouldn’t because the toInt would happen before passing the parameter to the queryParam method.
The solution here would be to pass a function:
session => session("latitude").validate[Int].
I have written this function which is called when a user clicks a link. The function basically creates a copy of the user data with one field altered (thus keeping the original value unchanged i.e. not-mutable) and then updates the database with the new value
def confirmSignupforUser(user:User):Future[Option[User]] = {
println("confirming user: "+user)
val newInternalProfile = user.profile.internalProfileDetails.get.copy(confirmed=true)//new data which should be added in the database
println("old internal profile: "+user.profile.internalProfileDetails.get)
println("new internal profile: "+newInternalProfile)
val newProfile = UserProfile(Some(newInternalProfile),user.profile.externalProfileDetails)
println("old profile: "+user.profile)
println("new profile: "+newProfile)
val confirmedUser = user.copy(profile=newProfile)
for(userOption <- userRepo.update(confirmedUser)) yield { //database operation
println("returning modified user:"+userOption)
userOption
}
}
To test the code, I have written the following spec
"confirmSignupforUser" should {
"change confirmed status to True" in {
val testEnv = new TestEnv(components.configuration)
val externalProfile = testEnv.externalUserProfile
val internalUnconfirmedProfile = InternalUserProfile(testEnv.loginInfo,1,false,None)
val internalConfirmedProfile = internalUnconfirmedProfile.copy(confirmed=true)
val unconfirmedProfile = UserProfile(Some(internalUnconfirmedProfile),externalProfile)
val confirmedProfile = UserProfile(Some(internalConfirmedProfile),externalProfile)
val origUser = User(testEnv.mockHelperMethods.getUniqueID(),unconfirmedProfile)
val confirmedUser = origUser.copy(profile = confirmedProfile)
//the argument passed to update is part of test. The function confirmSignupforUser should pass a confirmed profile
when(testEnv.mockUserRepository.update(confirmedUser)).thenReturn(Future{Some(confirmedUser)})
//// await is from play.api.test.FutureAwaits
val updatedUserOption:Option[User] = await[Option[User]](testEnv.controller.confirmSignupforUser(origUser))
println(s"received updated user option ${updatedUserOption}")
updatedUserOption mustBe Some(confirmedUser)
}
}
I am not confident if I am testing the method correctly. The only way I can check that the confirmed field got changed is by looking at the return value of confirmSignupforUser. But I am actually mocking the value and I have already set the field confirmed to true in the mocked value (when(testEnv.mockUserRepository.update(confirmedUser)).thenReturn(Future{Some(confirmedUser)}).
I know the code works because in the above mock, the update method expects confirmedUser or in other words, a user with confirmed field set to true. So if my code wasn't working, update would have been called with user whose confirmed field was false and mockito would have failed.
Is this the right way to test the method or is there a better way?
You don't need to intialize internalConfirmedProfile in your test. The whole point is to start with confirmed=false, run the confirmSignupforUser method, and make sure that the output is confirmed=true.
You should check 2 things:
check that the return value has confirmed=true (which you do)
check that the repository has that user saved with confirmed=true (which you don't check). To check that you would need to load the user back from the repository at the end.
I want to call value of 'myActionID' variable. How do I do that?
If i pass static value like "actionId":1368201 to myActionID then it works, but If I use "actionId" : ${actionIdd} it gives error.
Here's the relevant code:
class LaunchWorkflow_Act extends Simulation {
val scenarioRepeatCount = 1
val userCount = 1
val myActionID = "13682002351"
val scn = scenario("LaunchMyFile")
.repeat (scenarioRepeatCount) {
exec(session => session.set("counter", (globalVar.getAndIncrement+" "+timeStamp.toString())))
.exec(http("LaunchRequest")
.post("""/api/test""")
.headers(headers_0)
.body(StringBody(
"""{ "actionId": ${myActionID} ,
"jConfig": "{\"wflow\":[{\"Wflow\":{\"id\": \"13500145349\"},\"inherit-variables\": true,\"workflow-context-variable\": [{\"variable-name\": \"externalFilePath\",\"variable-value\": \"/var/nem/nem/media/mount/assets/Test.mp4\"},{\"variable-name\": \"Name\",\"variable-value\": \"${counter}\"}]}]}"
}""")))
.pause(pause)
}
}
setUp(scn.inject(atOnceUsers(userCount))).protocols(httpProtocol)
Everything works fine If I put value 13682002351 instead of myActionID. While executing this script in Gatling I am Getting this error
ERROR i.g.http.action.HttpRequestAction - 'httpRequest-3' failed to
execute: No attribute named 'myActionID' is defined
Scala has various mechanisms for String Interpolation (see docs), which can be used to embed variables in strings. All of them can be used in conjunction with the triple quotes """ used to create multi-line strings.
In this case, you can use:
val counter = 12
val myActionID = "13682002351"
val str = s"""{
"actionId": $myActionID ,
"jConfig": "{\"wflow\":[{\"Wflow\":{\"id\": \"13500145349\"},\"inherit-variables\": true,\"workflow-context-variable\": [{\"variable-name\": \"externalFilePath\",\"variable-value\": \"/var/nem/nem/media/mount/assets/Test.mp4\"},{\"variable-name\": \"Name\",\"variable-value\": \"${counter}\"}]}]}"
}"""
Notice the s prepended to the string literal, and the dollar sign prepended to the variable names.
Using S interpolated String we can do this easily:
s"""Hello Word , Welcome Back!
How are you doing ${userName}"""
Hey there I am trying to make my first class my code is as follows:
class Twitt:
def __init__(self):
self.usernames = []
self.names = []
self.tweet = []
self.imageurl = []
def twitter_lookup(self, coordinents, radius):
twitter = Twitter(auth=auth)
coordinents = coordinents + "," + radius
print coordinents
query = twitter.search.tweets(q="", geocode='33.520661,-86.80249,50mi', rpp=10)
print query
for result in query["statuses"]:
self.usernames.append(result["user"]["screen_name"])
self.names.append(result['user']["name"])
self.tweet.append(h.unescape(result["text"]))
self.imageurl.append(result['user']["profile_image_url_https"])
What I am trying to be able to do is then use my class like so:
test = Twitt()
hello = test.twitter_lookup("38.5815720,-121.4944000","1m")
print hello.usernames
This does not work and I keep getting: "AttributeError: 'NoneType' object has no attribute 'usernames'"
Maybe I just misunderstood the tutorial or am trying to use this wrong. Any help would be appreciated thanks.
I see the error is test.twitter_lookup("38.5815720,-121.4944000","1m") return nothing. If you want the usernames, you need to do
test = Twitt()
test.twitter_lookup("38.5815720,-121.4944000","1m")
test.usernames
Your function twitter_lookup is modifying the Twitt object in-place. You didn't make it return any kind of value, so when you call hello = test.twitter_lookup(), there's no return value to assign to hello, and it ends up as None. Try test.usernames instead.
Alternatively, have the twitter_lookup function put its results in some new object (perhaps a dictionary?) and return it. This is probably the more sensible solution.
Also, the function accepts a coordinents (it's 'coordinates') argument, but then throws it away and uses a hard-coded value instead.
