Introduction
I figured out that there is no library in .NET Framework which allows to generate random values of predefined types. I decided to create Some library which generates most random values of predefined types like decimal
, float
, string
, etc. with many options of generating.
This is to generate random values in UnitTests and database values.
How To Get It?
You can download the source code from GitHub or nuget by typing Some keyword. See the screenshot below.
How To Use It?
When you get the newest version, now you can random values of predefined types. Let's see some examples.
Default seed value
static Some()
{
RandomCharacters = new StringBuilder();
randomizer = new Random((int)DateTime.Now.Ticks);
}
Positive float
float floatValue = Some.PositiveFloat();
will generate random value from 0 to max float.
Negative float
float floatValue = Some.NegativeFloat();
will generate random float value from min float to 0.
Float with range
float floatValue = Some.Float(99.1f, 341.21f);
will generate float random value between 99.1f and 341.21f.
Future date and time
DateTime futureDate = Some.FutureDate();
will return newer date and time when invoked.
Past date and time
DateTime pastDate = Some.PastDate();
will return older date and time when invoked.
Date with range
DateTime date = Some.Date(DateTime.Now, DateTime.Now.AddDays(10))
will generate date withing specified range in input parameters of invoking method.
String (only letters)
string randomString = Some.String(20);
will generate string
with 20 random characters.
Lowercase string (only letters)
string randomString = Some.StringLower(20);
will generate 20 lowercase characters as string
.
Uppercase string (only letters)
string randomString = Some.StringUpper(20);
will generate 20 uppercase characters as string
.
String with digits
string randomString = Some.DigitsAsString(20);
will generate 20 digits as string
.
Integer
int randomInteger = Some.Integer();
will return random integer value.
Integer within range
int randomInteger = Some.Integer(100, 456);
will return random integer value between 100 and 456;
Positive integer
int positiveInteger = Some.PositiveInteger();
will return random positive integer value.
Negative integer
int negativeInteger = Some.NegativeInteger();
will return random negative integer value.
Double
double randomDouble = Some.Double();
will return random double value.
Double within range
double randomDouble = Some.Double(1.765d, 100.091892d);
will return random double value between 1.765d and 100.091892d.
Positive double
double randomDouble = Some.PositiveDouble();
will return only positive double value.
Negative double
double randomDouble = Some.NegativeDouble();
will return only negative double value.
Decimal
decimal randomDecimal = Some.Decimal();
will return random decimal value.
