I have a list of things, each of which might be a foo or a bar. I want to build some xml that looks like this:
<rdf:RDF>
<foo id="1">
<foo id="2">
<bar id="3">
</rdf:RDF>
So I have gotten this far:
MarkupBuilder xml = new MarkupBuilder(writer)
xml.'rdf:RDF' (nsmap) { }
But now I am stuck. How do i - within that xml.'rdf:RDF' (nsmap) { } closure - iterate over my list of stuff? How do i - within that iterator - spit out a foo or a bar element as applicable?
Its simpler as you may think. Include a loop in the xml closure and in turn include markup in the loop. This script ...
import groovy.xml.MarkupBuilder
things = ['foo','foo','bar']
writer = new StringWriter()
xml = new MarkupBuilder(writer)
xml.'rdf:RDF' {
things.eachWithIndex {thing,index ->
"$thing" id:index+1
}
}
println writer
... will produce following output:
<rdf:RDF>
<foo id='1' />
<foo id='2' />
<bar id='3' />
</rdf:RDF>
Here You go:
import groovy.xml.MarkupBuilder
import org.custommonkey.xmlunit.*
def data = [foo:1,bar:2,baz:3]
def writer = new StringWriter()
def xml = new MarkupBuilder(writer)
xml.'rdf:RDF' {
data.each { e ->
"$e.key"(id:e.value)
}
}
println writer
Ok.
The issue is that when a closure is run by a builder, it operates within the context of the builder. Now, it turns out that the builder context hides methods, but does not hide variables. This means that you can create a closure, assign it to a variable, and access it from within the builder.
NOw, I get the impression that this closure, too, runs in the context of the builder. But I suspect you can assign "this" to a variable outside the closures and then access that variable to get the context back.
It's ridiculous that you have to go to this sort of trouble. Im reminded of coding in Microsoft Access, back in the 90's. It works great, until the moment when you want to do something more than it was strictly designed to do.

When following the geb page object pattern, it is encouraged to create a static block of values that represent the elements on the page you are attempting to interface with. It is also good to create an at checker. Here is an example:
class SomePage extends Page{
static at = {$(By.xpath("some header or something")).displayed}
static content = {
element1 {$(By.xpath("some xpath1"))}
element2 {$(By.xpath("some xpath2"))}
//so on and so forth
}
}
Now I think I know the answer this question already but could not find the docs to back it up. I am pretty sure that the static content block is initialized once the "at checker" is called from a test script, but I am not sure. If what I am suggesting is true then that would mean something like this:
class SomePage extends Page{
static at = {$(By.xpath("some header or something")).displayed}
def someString
static content = {
element1 {$(By.xpath("//*[contains(text(), ${someString}"))}
element2 {$(By.xpath("some xpath2"))}
//so on and so forth
}
def setSomeString(String x){
this.someString = x
}
}
would be impractical right, or maybe even impossible? This is because in order to call "setSomeString" you need to call the at checker to tell the script which class to reference for method and variable calls, but if you call the at checker that means the static content becomes initialized.
Furthermore, if a webpage has content that doesn't show up upon initial arrival to the webpage, then you would not be able to put that content into the static content block either, since the at checker should be called as soon as you arrive on said webPage.
I am simply looking to confirm or deny that this is the behavior of geb page object. and I would be happy to hear answers describing best practice given the above situation.
also if there is a way to re-initialize the content, I would like to know that too, but I figure there is not.
A content definition is evaluated every time the result of the definition is requested:
def somePage = to SomePage //at checker is executed but the defintion for element1 isn't
somePage.element1 // closure defined for element1 is executed
somePage.element1 // and here again
// many lines of code which trigger additional content to show up on the page
somePage.element1 // closure defined for element1 is executed again
I'm trying to do something in SoapUi with Groovy and it's not working.
I have multiple nodes with many attributes and I need to extract the child node attribute based of a parent's attribute
For example:
<library id="82389389">
<book id="123" bookType="SF">
<price id="325" priceValue="5"/>
</book>
<book id="4741" bookType="History">
<price id="12388" priceValue="15"/>
</book>
<book id="2626" bookType="Drama">
<price id="12145" priceValue="40"/>
</book>
</library>
In this XML I need to extract priceValue based on the bookType and use it somewhere else (the order of the book nodes is changing)
I tried this but it doesn't work:
def response = .../library[1]
def i=0
def records = new XmlSlurper().parseText(response)
def size = records.book.size()
for (i=0,i<size,i++)
{
bookType1 = records.book[i].#bookType.first().value().text();
if (bookType1 == 'History')
{
def priceValueBook = records.book[i].price.#priceValue.first().value().text()
log.info priceValueBook
}
}
It's not clear exactly at what point you are trying to do this, but the following would work in SoapUI script step:
context.expand('${test_step#Response#//*:book[#bookType="History"]/*:price/#priceValue}')
I have a DSL that looks like this:
aMethod {
"a name"
"another name"
"and a third name"
}
My Problem is that I'm unable to access the three string, because calling the closure only returns the last statement. I tried to override the constructor of String(char[] value) which is called when an anonymous String-statement occurs:
def original
// primitive way to get the String(char[])-constructor
String.class.constructors.each {
if(it.toString() == "public java.lang.String(char[])") {
original = it
}
}
// overriding the constructor
String.metaClass.constructor = { char[] value ->
def instance = original.newInstance(value)
// ... do some further stuff with the instance ...
println "Created ${instance}"
instance
}
// teststring to call String(char[] value)
"teststring"
Unfortunately it didn't work and I thought anyway that it is quite complicated.
Thank you for the comments. Actually it would be great to define everything without quotes. But: After having a dsl that can be translated to java objects I'd loved to have additional annotations in my language at development time. I want to annotate duplicate names and so on. The IDE's I know better, Intellij and Eclipse handle Strings "a name" as one PSI-Elements. Splitting these elements can be very inconvinient ... I guess. I think statements in a closure like aMethod {a name} would result in an interpretation like aMethod {a.name}. That would mean that instead of having a StringLiteral Psi "a name", I would have an Object-Psi and a MethodCall-Psi or something like that. I don't know, and my next goal is just "parsing/creating" my java objects. Are you sure that it is impossible to override the String-Constructor?
Is any constructor called when you have a groovy script with this content:
"hello World"
class Parent {
final static String newLine = "*"
}
class Child extends Parent{
List body = [3, 4, 5]
String toString() {
def str = new StringBuilder()
body.each { str.append(it + newLine) }
str
}
}
def c = new Child()
println c
The above is one trivial sample to illustrate the problem. It couldn't be compiled using Groovy plugin on Eclipse. Remove either final or static in the field of super class solves the problem. However, I have no idea why it's the case.
http://groovy.codehaus.org/Groovy+Beans
In this link it mentions the rules for property and fields used in Groovy. I suppose the one applied should be the last one, i.e. meta class. Unfortunately, I still couldn't understand the behavior.
The behavior is reproduced consistently in all versions of Groovy. Maybe someone could report one bug to Groovy team. I have never done this before. It would be more efficient if someone experienced could do that.
This is most probably https://issues.apache.org/jira/browse/GROOVY-5776 which is more difficult to fix than it looks like
As blackdrag already pointed out: it's a bug.
But another workaround is to add the protected keyword:
protected final static String newLine = "*"
I'm getting a text which contains ${somethingElse} inside, but it's just a normal String.
I've got a class:
class Whatever {
def somethingElse = 5
void action(String sth) {
def test = []
test.testing = sth
assert test.testing == 5
}
}
Is it possible with groovy?
EDIT:
my scenario is: load xml file, which contains nodes with values pointing to some other values in my application. So let's say I've got shell.setVariable("current", myClass). And now, in my xml I want to be able to put ${current.someField} as a value.
The trouble is, that the value from xml is a string and I can't evaluate it easily.
I can't predict how these "values" will be created by user, I just give them ability to use few classes.
I cannot convert it when the xml file is loaded, it has to be "on demand", since I use it in specific cases and I want them to be able to use values at that moment in time, and not when xml file is loaded.
Any tips?
One thing you could do is:
class Whatever {
def somethingElse = 5
void action( String sth ) {
def result = new groovy.text.GStringTemplateEngine().with {
createTemplate( sth ).make( this.properties ).toString()
}
assert result == "Number 5"
}
}
// Pass it a String
new Whatever().action( 'Number ${somethingElse}' )
At first, what we did, was used this format in xml:
normalText#codeToExecuteOrEvaluate#normalText
and used replace closure to regexp and groovyShell.evaluate() the code.
Insane. It took a lot of time and a lot of memory.
In the end we changed the format to the original one and crated scripts for each string we wanted to be able to evaluate:
Script script = shell.parse("\""+stringToParse+"\"")
where
stringToParse = "Hello world # ${System.currentTimeMillis()}!!"
Then we were able to call script.run() as many times as we wanted and everything performed well.
It actually still does.
