Kembali kuliah selepas cuti Aidiladha. Kami tak tidur malam siapkan prototaip perisian. Tapi bila masuk kelas, En Juhazreen kata hari ni dia nak ajar Testing and Evaluation...
Lega. Present ditangguhkan minggu depan...
Secara ringkasnya, proses pengujian perlu dilaksanakan berdasarkan beberapa faktor utama, antaranya :
- mengelakkan kegagalan aplikasi semasa digunakan oleh pengguna
- mengelakkan kerugian dari segi kos dan masa pembangunan
- membolehkan kualiti sesebuah aplikasi dipertingkatkan lagi
Pengujian bermaksud menjalankan penilaian atau pemerhatian terhadap aplikasi yang dibangunkan untuk menentukan samada ia menepati spesifikasi yang telah ditetapkan serta memenuhi kehendak pengguna.
Ini termasuklah dari sudut struktur dan isi kandungan aplikasi, rekabentuk antaramuka dan sistem penerokaan, interaktiviti dan sebagainya.
Terdapat dua fasa pengujian utama yang sering dilaksanakan iaitu :
- pengujian pembangunan - dilakukan semasa proses pembangunan dilaksanakan
- pengujian penerimaan - dilakukan untuk memastikan perisian dibina mampu beroperasi tanpa sebarang kegagalan.
Testing and evaluating can help you spot problems and make appropriate changes.
It helps to have somebody else evaluate and test the courseware for you, but you can probably gain some benefit even if you go through the procedure yourself.
Evaluation –uji, nilai, dilaksakan oleh pakar – melihat secara keseluruhan perisian tersebut(content, performance)
a. What is working well; what are the strengths of the project; what are he clients saying about it;
b. What do they like or dislike; is the objective being accomplished
c. If the entire project
Testing – to check performace to find error
a. Adakah design dokumen berjaya diimplemen
b. Adakah kdgn perisian difahami
c. Adakah semua multimedia and interactive elements work properly
d. Everything that is used in the presentation is relevent to the intended audience, if not then what part ia to be changed
What is testing
a. examining the project performance according to specifications that have been agreed
b. This will include the robustness (keutuhan)of the code, the structure and content, the interface, the interactivity, the look and the feel.
c. There are so many types that can be aplied at every stage of a project
d. Also, the mix of disciplines in multimedia means that different approaches to testing might be employed.
Test plan
a. provide a checklist of all the functionality in the program
b. with such a checklist, testing
c. using structuredtesting method, a creative courseware tester can find a potentially serious problem then give programmers helpful
Phase involved in test plan –interface, function, usability, feedback
Alpha testing – ujian antara pembangun, kwn
Beta testing – ujian kepada pengguna, pakar
Development testing – the overall structure, text, audio and video scripts, the audio and video edits,
the look of the graphics, the look and the feel of the navigation
