This document contains some basic concepts and definitions about software testing. It has been written for studying a part of the Software Engineering Project course at my University. It is composed by a summary of the intersection of more than 10 different sources, all of which are cited. If you feel that some contents of this publication belong to your intellectual property and it is not cited, please contact the author who is willing to correct any mistake.
The first part of the paper focuses on the definition of the most important key aspects of software testing. Then some information about input partitioning are given. What follows is a research about code coverage and two useful and famous tools, Control-flow coverage and Data-flow analysis. A complete example on using those tools is then given. The second half of the document also contains the definition of the most important software testing practices.
The goal of this tiny document is to clarify key terms and therefore become a base start for the reader to go in deep with the interested topics. Another goal is to give a simple but clear example about data flow analysis, as I realized that not all the people understand the examples around the Net.
Software Testing is an empirical investigation conducted to provide stakeholders with information about the quality of the product or service under test, with respect to the context in which it is intended to operate. Software Testing also provides an objective, independent view of the software to allow the business to appreciate and understand the risks at implementation of the software. Test techniques include, but are not limited to, the process of executing a program or application with the intent of finding software bugs. It can also be stated as the process of validating and verifying that a software program/application/product meets the business and technical requirements that guided its design and development, so that it works as expected and can be implemented with the same characteristics. 1
So much time since my last post! I’m sure that the best way to come back to blog posting is a nice tutorial.
I’m going to write how to have the same home directory shared between Mac Os X and Gnu/Linux. Let me call Gnu/Linux just Linux from now on.
The configuration I’m proposing should be very confortable, as it works with symbolic links.
It lets you to boot either Mac Os X or Linux and have the same directories and files for your everyday use. Meanwhile, the important configuration files and directories (e.g. ~/Library for Mac Os X, ~/.config for Linux) are kept separately on their corresponding partitions.
Another advantage of this configuration is that you can have a small partition dedicated to Linux – let’s say 10GB but could be even less – just for installing the programs you need, while your videos, documents, music files are kept inside the biggest partition, the one for Mac Os X.
Basically, you will mount your Mac Os X root partition in Linux, and soft-link your important directories to your Linux home directory.
You will then use them as there were real directories in your Linux home directory. For this how to, there are a couple of things I assume that:
disk0s2 /dev/sda2 MacOsx /
disk0s3 /dev/sda3 Linux /
disk0s4 /dev/sda4 Swap
Follow these instructions under Mac Os X:
Open a Terminal.
Identify your Mac Os X root partition:
/dev/disk0
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *111.8 Gi disk0
1: EFI 200.0 Mi disk0s1
2: Apple_HFS MacOsX 99.9 Gi disk0s2
3: EFI 10.7 Gi disk0s3
4: Linux Swap 1.0 Gi disk0s4
Disable file system journaling for the partition:
Do a ls -n of your home directory to discover your user id uid:
total 0
drwx——+ 11 501 20 374 25 Feb 17:43 Desktop
drwxrwxrwx+ 32 501 20 1088 26 Feb 18:19 Documents
drwxrwxrwx+ 8 501 20 272 26 Feb 18:06 Downloads
[Few Others ...]
My UID is 501. Keep your UID in mind, you will need it under Linux. You obtain the same results by using the command “id”.
Reboot your Mac.
Follow these instructions in a linux shell.
Change your Linux user id (UID). To correctly share the same home directory between both OS, you need to have on Linux the same UID of your Mac Os X user.
(sudo usermod -u 501 bodom_lx in my case)
To have your new UID applied, either reboot or logout from every shell you opened, even from your desktop environment. Login again.
Create a directory in which you are going to mount Mac Os X root partition:
put this line at the end of /etc/fstab, as root, with your favourite editor:
/dev/sda2 /media/MacOsX hfsplus rw,nosuid,nodev,uhelper=hal 0 0
Remember to change sda2 and MacOsX
Either reboot the system or type:
To mount your Mac Os X root directory in your mount point directory.
Now cd to your Linux home directory and begin to soft-link all of your important Mac Os X directories. Here are some of those I needed:
Don’t soft-link the Library directory.
Now you have the same important files shared on both Mac Os X and Linux, while the important hidden configuration files are kept in separate phyisical places.
You can listen to your Itunes mp3 collection on both operating systems. You can now develop programs under Gnu/Linux. You can reboot your machine to Mac Os X and take notes during the lectures, and so on! Hope you liked this how to, and comment it as well. Contact me if you find some mistakes or you’re in trouble!
This guide will help you to install OpenGEU and every other Ubuntu based linux distribution on your Macbook (either “normal” or pro). Even Ubuntu will work with this how-to.
The tutorial is aimed on how to succesfully partition the hard disk and to correctly boot the distribution. For a better post-install configuration I suggest you to follow the Ubuntu Wiki.
