Apart from that‚ animal testing also has poor results in both drug testing experiment or medical research. This is because the anatomic‚ metabolic and cellular differences of animal and human are very much different from each other which makes them as poor test subject for human beings. Consequently‚ these absurd experimentation are unable to generate and predict accurate result that may occur in human beings. For instance‚ cancer has an abysmal record of failures where both humans and animals react

White-Box Testing White-box testing is a verification technique software engineers can use to examine if their code works as expected. In this chapter‚ we will explain the following: • a method for writing a set of white-box test cases that exercise the paths in the code • the use of equivalence partitioning and boundary value analysis to manage the number of test cases that need to be written and to examine error-prone/extreme “corner” test cases • how to measure how thoroughly the test

This essay will discuss the dilemmas of testing drugs on human beings‚ as well as the dilemmas once we shift testing drugs on animals. There are several ethical dilemmas when it comes to testing drugs on people in general. A number of the tests can be potentially life threatening. The new drugs may cause severe reactions which might not be treatable later on. For years‚ scientists have been experimenting on humans. The majority that were used for testing were the insane‚ prisoners‚ and charity patients

experimentation is a contentious issue‚ but it boils down to two essential questions: does it work‚ and is it ethical? The first is easy to answer: it works. Some would have you believe there are alternatives for all animal research‚ or that animal testing is always misleading and unsafe. These are fallacies. Where there are reliable alternatives‚ of course‚ we use them - that’s what the law demands. Magnetic resonance imaging‚ computer models and work on isolated tissues and cell cultures can be

should be able to perform drug tests for all students especially student athletes. There are lots of benefits of drug testing. For example‚ because of drug testing in schools‚ students learn drugs are dangerous and they break the law by using them. The results from the drug tests would show if students have or haven’t done drugs. There are hundreds of benefits because of drug testing in schools. Schools performing random drug tests can prevent accidents and overdosing. Drug tests can help catch the
