Examples

#reproducer:::testfunctionParameterChecks(alternative='larger',alpha=0.1,stderr=0.002)
#Error in testfunctionParameterChecks(alternative = 'larger', alpha = 0.1) :
#  Invalid alternative parameter, choose one of two.sided, greater or less
reproducer:::testfunctionParameterChecks(alternative='greater',alpha=0.1,stderr=0.002)
#[1] 'Success'
#reproducer:::testfunctionParameterChecks(alternative='greater',alpha=0.1,stderr=0.000)
#Error in testfunctionParameterChecks(alternative = 'greater', alpha = 0.1,  :
#  Improbably small variance, data are essentially constant
