I'm trying to use Instancio to generate data for testing. The Student class has a birthdate member as a String type to store the date in the format YYYYMMDD.
How can I use Instancio library (test data generator) to generate a date in the format yyyyMMdd as string?
Here was my starting point:
Student student = Instancio.of(Student.class)
.generate(field(Student::getBirthdate), gen -> gen.temporal().localDate().past())
.create();
Thx
As suggested in the comments, it's a good practice to declare the field as a LocalDate
instead of a String
. If you cannot change that, you can map the date to a string using the as()
method:
Student student = Instancio.of(Student.class)
.generate(field(Student::getBirthdate), gen -> gen.temporal().localDate().past().as(dob -> dob.format(DateTimeFormatter.BASIC_ISO_DATE)))
.create();
