Workaround for Apex switch bug when multiple values and one of them is null?
The switch
returns the wrong value for null
for this case where there are multiple when
values and one of them is null
in API 43.0:
@IsTest
static void test() {
// Desired outcomes
System.assertEquals(1, f('a'));
System.assertEquals(2, f('b'));
System.assertEquals(2, f('c'));
System.assertEquals(3, f('d'));
System.assertEquals(0, f(''));
System.assertEquals(0, f(null)); // Fails
}
private static Integer f(String s) {
// Incorrectly returns 3 for null
switch on s {
when null, '' { return 0; }
when 'a' { return 1; }
when 'b', 'c' { return 2; }
when else { return 3; }
}
}
Is there a workaround for this?

I don't suppose you've logged a bug for this? I'm sure @ca_peterson would love to know about this (if he doesn't already).

@sfdcfox If you mean via a case, sure I'll do that next week unless someone says it is already known.

One workaround is to separate the values. All the asserts pass for this code:
private static Integer f(String s) {
// Correctly returns 0 for null
switch on s {
when null { return 0; }
when '' { return 0; }
when 'a' { return 1; }
when 'b', 'c' { return 2; }
when else { return 3; }
}
}
PS
I've reported this bug to Salesforce via case 21246533.
