Your testing consists of three main elements:
• Testing using the performance indicators (within analysis) to prove that your solution does what your client wants it to do.
• Testing through development; this is testing the solution as you develop it.
• Testing during operation; this is using the test plan.
▫ During this section we can test the solution further.
▪ Unit testing – each individual element is tested and then the elements combined are tested to check the data flows properly.
▪ System testing – the whole system is tested.
• User testing – this is where the end user tests the system as though it were in real life to see if everything works as it should.
Difference between Personal and Technical skills
Personal skills: Sometimes referred to as ‘personal transferable skills’, these are skills that are learnt in one situation, but can also be put into practice in another situation. Examples of these include communication, team work, leadership and problem solving.
Technical skills: Knowledge and skills specific to a particular occupation or group of occupations. For example, the technical skills for a software developer would be programming skills.
Definitions
Key Definitions in this chapter that you will need to know:
Continuous Stationary– long sheets of paper with perforations between the pages and down each side. There are sprocket holes down the side which enable the paper to be pulled through the printer.
Impact printer– the shape of the letters is formed b y hitting a inked ribbon against the page.
Printer driver– software that converts commands from the systems or applications software into form that a particular printer can understand.
A test plan uses test data that ensures:
• The validity of the data input.
• The accuracy of the data input.
• The presentation of the output.
• That the solution meets the needs of the client.
• That the solution is usable by the end user and / or intended audience.
• That it incorporates the data to be used for testing the solution and the expected results of each test.
Introduction:
Testing should be done throughout the development of the solution. The reason for the test plan is because you would not want to proceed onto the next part of a solution unless you were sure that the first part worked properly. It is vital to keep tracking of all the tests you have performed. This is then put together in a document called a test plan.CHARACTERISTICS OF USERS
What is ICT?
ICT is the use of technology for the input of data, storage, processing to change the data into information, transfer of data to other devices and the output of information.
Problems caused by using ICT equipment:
Stress
This is a major factor in work-related illness. Symptoms can include headaches, stomach ulcers, sleeplessness and
loss of appetite.
ICT systems put additional pressure on employees:
• They may be used to monitor performance.
• They induce fear and panic particularly in older people.
• Constantly bring about the need to perform new tasks that you may not be able to cope with.
• It can be impossible to escape them.
• Information overload.
• New software can be difficult to use
RSI (Repetitive Strain Injury)
Caused by excess use of a keyboard, mouse and even mobile phones (used for texting) and can usually affect the
hands, wrists, elbows, arms, shoulders and / or neck. It can be very painful and debilitating. Once it develops, it
tends to recur. This is caused by repeated similar movements and incorrect use of the keyboard, i.e. resting the
wrists on the desk whilst typing. Many laptops have a built in wrist rest due to the positioning of the keyboard
and are therefore better to use. Ways of reducing RSI is to have a wrist rest, take frequent breaks and have the
keyboard at the right height.
Eyestrain
Brought on by long hours spent in front of a screen. Although there is no evidence that computers cause
permanent damage, they do accelerate current problems.
Factors that could contribute to eyestrain are:
• Glare from lighting affecting the screen.
• Lighting that shines directly on the screen or causes shadows.
• Constantly refocusing – i.e. looking down at a paper and back to the screen.
• Sitting too close to the screen – should be about 2 – 3 feet away.
Eyestrain can be prevented or reduced by taking regular breaks from working at the computer, every 10 minutes
or so looking into the distance and therefore relaxing the muscles of the eye, use blinds to reduce the glare on the
screen and sit at least 3 feet from the screen.
