Input data type check

x with the wrong data type while providing reasonable values for other arguments

• character string
• numeric number

ratio with the wrong data type while providing reasonable values for other arguments

• character string
• negative integer
• positive fraction number

roundUpFinal with wrong data type while providing reasonable values for other arguments

• character string
• numeric value

Output check

• Survival design

Case 1: 2 interim analyses and 1 final analysis, efficacy only, ratio = 1
Case 2: 2 interim analyses and 1 final analysis, efficacy only, ratio = 2
Case 3: 2 interim analyses and 1 final analysis, efficacy only, ratio = 0
Case 4: 2 interim analyses and 1 final analysis, efficacy only, ratio = 1, roundUpFinal = FALSE
Case 5: 3 interim analyses and 1 final analysis, IA1 binding futility, efficacy elsewhere, ratio = 1
Case 6: 3 interim analyses and 1 final analysis, IA1 non-binding futility, efficacy elsewhere, ratio = 1

• Binomial design

Case 1: 1 interim analysis and 1 final analysis, efficacy only, ratio = 1
Case 2: 2 interim analyses and 1 final analysis, efficacy only, ratio = 2
Case 3: 2 interim analyses and 1 final analysis, efficacy only, ratio = 2, roundUpFinal = FALSE
