For example, you could create a table of 5 rows and 2 colums like this:
import org.scalatest.prop.Tables._Because you supplied 2 members in each tuple, the type you'll get back will be a
val examples = Table( ("a", "b"), ( 1, 2), ( 2, 4), ( 4, 8), ( 8, 16), ( 16, 32) )
TableFor2
. If
you wanted a table with just one column you could write this:
val moreExamples = Table( "powerOfTwo", 1, 2, 4, 8, 16 )Or if you wanted a table with 10 columns and 10 rows, you could do this:
val multiplicationTable = Table( ("a", "b", "c", "d", "e", "f", "g", "h", "i", "j"), ( 1, 2, 3, 4, 5, 6, 7, 8, 9, 10), ( 2, 4, 6, 8, 10, 12, 14, 16, 18, 20), ( 3, 6, 9, 12, 15, 18, 21, 24, 27, 30), ( 4, 8, 12, 16, 20, 24, 28, 32, 36, 40), ( 5, 10, 15, 20, 25, 30, 35, 40, 45, 50), ( 6, 12, 18, 24, 30, 36, 42, 48, 54, 60), ( 7, 14, 21, 28, 35, 42, 49, 56, 63, 70), ( 8, 16, 24, 32, 40, 48, 56, 64, 72, 80), ( 9, 18, 27, 36, 45, 54, 63, 72, 81, 90), ( 10, 20, 30, 40, 50, 60, 70, 80, 90, 100) )The type of
multiplicationTable
would be TableFor10
. You can pass the resulting
tables to a forAll
method (defined in trait PropertyChecks
), to perform a property
check with the data in the table. Or, because tables are sequences of tuples, you can treat them as a Seq
.
Companion object that facilitates the importing of

members as an alternative to mixing it in. One use case is to importTables
members so you can use them in the Scala interpreter:
