I cannot understand why my simple String equality test is returning false.
Code is:
boolean isDevelopment() {
//config.project_stage is set to "Development"
String cfgvar = "${config.project_stage}"
String comp = "Development"
assert cfgvar.equals(comp)
}
Result is:
assert cfgvar.equals(comp)
| | |
| false Development
Development
I also get false if I do:
assert cfgvar == comp
toString() is not necessary. Most probably you have some trailing
spaces in config.project_stage, so they are retained also in cfgvar.
comp has no extra spaces, what can be seen from your code.
Initially the expression "${config.project_stage}" is of GString
type, but since you assign it to a variable typed as String,
it is coerced just to String, so toString() will not change anything.
It is up to you whether you use equals(...) or ==.
Actually Groovy silently translates the second form to the first.
So, to sum up, you can write assert cfgvar.trim() == comp.
You can also trim cfgvar at the very beginning, writing:
cfgvar = "${config.project_stage}".trim()
and then not to worry about any trailing spaces.
Have you checked for trailing spaces? At least your output as one for the first Development. Try a .trim() when you compare those strings (and maybe a .toLowerCase() too)
And remember: .equals() in Groovy is a pointer comparison. What want to do is ==. Yes, just the opposite from what it is defined in Java, but the Groovy definition makes more sense :-)
Update: see comment by @tim_yates - I mixed .equals() up with .is()
equals is not a pointer comparison in Groovy... You're thinking of is()On of the objects you comparing is not a String but GString, try:
cfgvar.toString().equals(comp)
However your code works with groovy v. 2.4.5. Which version are you using?
