Expression Syntax Description
- ${number@min@max}:number is a
fixed string, and
min,max are integers greater than
1 and less than 1000.
Generates a random number string, the string length range is
[min,max].
Example: ${number@5@10} Generates a string of random numbers with length range of [5,10]. -
${lower@min@max}:
lower is a fixed string, and
min,max are the length range of the
generated random string. Generates a random lowercase string.
Example: ${lower@5@10} Generates a random lowercase string with length range of [5,10]. -
${upper@min@max}:upper is a fixed
string, and
min,max are the length range of the
generated random string. Generates a random uppercase string.
Example: ${upper@5@10} Generates a random uppercase string with length range of [5,10]. -
${alphaNumber@min@max}: alphaNumber is a fixed
string, and min,max are random
string length range. Generate random uppercase, lowercase and
numeric strings.
Example: ${alphaNumber@5@10} Generate a string of random lowercase, uppercase and numbers with length range of [5,10]. -
${unicode@start@end@min@max}:
unicode is a fixed string. start
is a hexadecimal string (two bytes) with a length of 4 means the
starting Unicode character.
end is a hexadecimal string (two
bytes) with a length of 4,
means the ending Unicode character.
end needs to be greater than start. min,max
are the length range of the random Unicode string generated.
Generates a random Unicode string in the codepoint range.
