How to fill in empty double value in test DTO, Java, Spring

So I am testing the controller of my application and I stumbled upon a problem.
This is the Json I use in my testcode:
String bike = "{" +
" \"bikeNumber\" : \"E2\"," +
" \"brand\" : \"Gazelle\"," +
" \"frameNumber\" : \"HA1234568\"," +
" \"retailPrice\" : 1200," +
" \"basePrice\" : 20.0," +
" \"electric\" : true" +
"}";
I want to test when the user doesn't fill in one of the values, it throws an exception. In other words I want to test the #NotNull, #NotBlank annotations.
I have done this for bikeNumber and frameNumber, these are string types and I can leave them open. The problem I get if I leave the basePrice open and run my test, I get an error saying:
java.lang.AssertionError: No value at JSON path "$.basePrice"
I know that it's a null value because I haven't filled it in, but that is part of the plan. So my question is, how do I leave a long, double or int value empty without getting a test error.
My full code block is here:
#Test
void whenPostRequestNoBasePrice_thenBadRequestResponse() throws Exception {
String bike = "{" +
" \"bikeNumber\" : \"E1\"," +
" \"brand\" : \"Gazelle\"," +
" \"frameNumber\" : \"HA1234568\"," +
" \"retailPrice\" : 1200," +
" \"basePrice\" : \"\" " +
" \"electric\" : true" +
"}";
mockMvc.perform(MockMvcRequestBuilders.post("/createbike")
.content(bike)
.contentType(MediaType.APPLICATION_JSON))
.andExpect(status().isBadRequest())
.andExpect(jsonPath("$.basePrice", Is.is( "Base price is mandatory.")))
.andExpect(MockMvcResultMatchers.content().contentType(MediaType.APPLICATION_JSON)).andReturn().getResponse().getContentAsString();
}
I tried multiple things, also with and without the comma: "basePrice" : "" ," +
Also I can't seem to find this anywhere on stackoverflow.

I want to make a report command and send only the report part of the message and ignore arg[0] arg[1] and send arg[3 ] and up

So i want it to do send [sender] has reported [person] for [args[3] and up]
if (args[0].equalsIgnoreCase("!report")) {
event.getGuild().getTextChannelById("818967272731050024").sendMessage(event.getAuthor().getAsMention() + " has reported " + args[1].toString() + " for ' + event.getMessage().getContentDisplay()" + "'").queue();
event.getMessage().addReaction("👍").queue();
}

wait until angular 2+ has finished loading issue

I recently posted a question about an issue I have white testing an angular based application (ref: wait until Angular has finished loading issue )
Turns out that the check done was valid for angular 1.x apps, while our application runs on angular 6.x.
I've then found out that post: Detecting that Angular 2 is done running
which explains how to do a similar check but for angular 2+ apps. I've set up the check in a similar fashion to "Michal Filip" explained.
I've also tried to use the ngWebdriver solution proposed further down in the post.
Both suffers of the same problem: the check will always return true as in its done loading which isn't true.
tried to inverse the check, it didn't help (state never changed)
// Will check if Angular still has pending http_requests ongoing and wait if required
public void untilAngular2HasFinishedProcessing()
{
until(() ->
{
log.info("Waiting on angular 2+ to finish processing");
final boolean isReady = ((JavascriptExecutor) driver).executeAsyncScript(
"var callback = arguments[arguments.length - 1];" +
"if (document.readyState !== 'complete') {" +
" callback('document not ready');" +
"} else {" +
" try {" +
" var testabilities = window.getAllAngularTestabilities();" +
" var count = testabilities.length;" +
" var decrement = function() {" +
" count--;" +
" if (count === 0) {" +
" callback('complete');" +
" }" +
" };" +
" testabilities.forEach(function(testability) {" +
" testability.whenStable(decrement);" +
" });" +
" } catch (err) {" +
" callback(err.message);" +
" }" +
"}"
).toString().equals("complete");
log.info("Is angular 2+ ready? " + isReady);
return isReady;
}
);
}
// sample call would be
untilAngular2HasFinishedProcessing();
Excpected: the test would wait until Angular is done loading before returning true
Actual: Returns true from the start, which I know isn't the case.
Possible duplicate? No, because this is a problem question based on the implementation proposed in the linked question.

Here's the solution I ended up using:
public boolean untilAngular2HasFinishedProcessing()
{
until(() ->
{
log.info("Waiting on angular 2+ to finish processing");
final boolean isReady = (Boolean.valueOf(((JavascriptExecutor) driver)
.executeScript(
"try{" +
"return (window.getAllAngularTestabilities()[0]._ngZone.hasPendingMicrotasks == " +
"false && " +
"window.getAllAngularTestabilities()[0]._ngZone.hasPendingMacrotasks == false && " +
"window.getAllAngularTestabilities()[0]._ngZone._nesting == 0 &&" +
"window.getAllAngularTestabilities()[0]._ngZone.isStable == true)" +
"}" +
"catch(err) {" +
"if (err.message == ('window.getAllAngularTestabilities is not a function'))" +
"{" +
"return true" +
"}" +
"}")
.toString()));
log.info("Is Angular 2+ ready? " + isReady);
return isReady;
}
);
return true;
}
That worked on a consistent fashion so far.

Java Selenium with Angular 5

I am trying to work with Selenium in Java with Angular 5 based website.
Selenium does not support it directly, but JavascriptExecutor can help validating the page components finished loading.
The problem is, I do not know how to implement the JavaScript to validate this.
I am using:
return window.getAngularTestability === undefined
to validate Angular 5 exists in the current page, but the next part of the implementation is a mystery to me.
I know I have to use return window.getAngularTestability somehow.

You can create a generic java method for running any javascript within your Java code. Refer below block of code:-
public void executeJavascript(String script) {
((JavascriptExecutor) driver).executeScript(script);
}
You can pass your return javascript statements as parameters to this method.

I found an answer after a lot of research and searching the web.
The solution is not mine, so i do not deserve the credit.
ExpectedCondition<Boolean> expectation = driver -> ((JavascriptExecutor) driver).executeAsyncScript(
"var callback = arguments[arguments.length - 1];" +
"if (document.readyState !== 'complete') {" +
" callback('document not ready');" +
"} else {" +
" try {" +
" var testabilities = window.getAllAngularTestabilities();" +
" var count = testabilities.length;" +
" var decrement = function() {" +
" count--;" +
" if (count === 0) {" +
" callback('complete');" +
" }" +
" };" +
" testabilities.forEach(function(testability) {" +
" testability.whenStable(decrement);" +
" });" +
" } catch (err) {" +
" callback(err.message);" +
" }" +
"}"
).toString().equals("complete");
try {
WebDriverWait wait = new WebDriverWait(webDriver(), 15);
wait.until(expectation);
} catch (Throwable error) {
new Exception("Timeout waiting for Page Load Request to complete.");
}

Convert Loadrunner File Parameter to Java string for payload

I have a java virtual user script that is sending a payload request. I am trying to use values from a file to send via a loadrunner file parameter.
here is the payload:
private static final String PAYLOAD =
"<ips_cad_mdt>\n" +
" <SignOnRequest>\n" +
" <DestApplication>hhhh</DestApplication>\n" +
" <OrigApplication>hhh</OrigApplication>\n" +
" <SessionRef>3</SessionRef>\n" +
" <Aliasing>1234</Aliasing>\n" +
" </SignOnRequest>\n" +
"</ips_cad_mdt>";
I would like to use something like the following:
private static final String PAYLOAD =
"<ips_cad_mdt>\n" +
" <SignOnRequest>\n" +
" <DestApplication>hhh</DestApplication>\n" +
" <OrigApplication>hhh</OrigApplication>\n" +
" <SessionRef>3</SessionRef>\n" +
" <Aliasing>”+lr.eval_string(“{AliasId}”)+”</Aliasing>\n" +
" </SignOnRequest>\n" +
"</ips_cad_mdt>";
for some reason i cant see any output for this value. do i need to declare a variable: e.g. lr.save_string("AliasId", "{AliasId}");
an example of this would help loads. Many Thanks

There seems to be an error in the code completion in VuGen. The parameters should be reversed and without the {} in save_string.
lr.save_string("1234","myId");
lr.message(lr.eval_string("{myId}"));
In the documentation it is correct - https://admhelp.microfocus.com/lr/en/12.55/help/function_reference/FuncRef.htm#FuncRef/c_vuser/lrFr_lr_save_string.htm?Highlight=lr_save_string
I asked the responsible team to fix the code completion in VuGen so you will be able to see this change in one of the future releases.
