What and how much to test depends on how important it is to know that the tested software works right, in relation to how much time you are willing to dedicate to testing. since you are reading this, then for some reason you have decided to dedicate at least some time to unit testing.<o:p></o:p></span></div> <div class="MsoListParagraphCxSpLast" style="mso-list: l8 level1 lfo2; text-indent: -.25in;"> <span style="font-size: 12.0pt; line-height: 115%; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin;"><br></span></div> <div class="MsoNormal"> <span style="font-size: 12.0pt; line-height: 115%; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin;">Example<o:p></o:p></span></div> <div class="MsoNormal"> <span style="font-size: 12.0pt; line-height: 115%; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin;"><br></span></div> <div class="MsoListParagraphCxSpFirst" style="margin-left: 40.85pt; mso-add-space: auto; mso-list: l0 level1 lfo3; text-indent: -.25in;"> <span style="font-family: Wingdings; font-size: 12.0pt; line-height: 115%; mso-bidi-font-family: Wingdings; mso-fareast-font-family: Wingdings;">ü<span style="font-family: 'Times New Roman'; font-size: 7pt; line-height: normal;">  </span></span><span style="font-size: 12.0pt; line-height: 115%; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin;">I’m Currently developing an SMTP server. An SMTP server needs to handle email address of the format specified in RFC documents. To be confident that my SMTP server compiles with the RFC, I need to write a test case for each allowable email address type specified in the RFC. In the RFC says that the character “#” is prohibited, then I should write a test case that sends an address with “#” and verifies that the SMTP server rejects it. You don’t need to have a formal specification document to work from. If I wasm’t aiming for compliance, I could just decide that it’s good enough if my server accepts email address consisting only of letters, numbers and “@”, without caring whether other addresses succeed or fail.<o:p></o:p></span></div> <div class="MsoListParagraphCxSpLast" style="margin-left: 40.85pt; mso-add-space: auto; mso-list: l0 level1 lfo3; text-indent: -.25in;"> <span style="font-family: Wingdings; font-size: 12.0pt; line-height: 115%; mso-bidi-font-family: Wingdings; mso-fareast-font-family: Wingdings;">ü<span style="font-family: 'Times New Roman'; font-size: 7pt; line-height: normal;">  </span></span><span style="font-size: 12.0pt; line-height: 115%; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin;">Another important point to understand is that everything is better if you make your tests before you implement the features. For my SMTP server, I did some prototyping first to make sure that my desing will work, but I did not attempt to satisfy my requirements with that prototype. I am now writing up my test cases and running them against existing SMTP server implementations(like Send mail). When I get to the implementation stage my work will be extremely well defined.Once my implementation satisfies all of the unit tests, just like send mail does then my implementation will be completed.<o:p></o:p></span></div> <div class="MsoListParagraphCxSpLast" style="margin-left: 40.85pt; mso-add-space: auto; mso-list: l0 level1 lfo3; text-indent: -.25in;"> <span style="font-size: 12.0pt; line-height: 115%; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin;"><br></span></div> <div class="MsoNormal"> <span style="font-size: 12.0pt; line-height: 115%; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin;">Note: Every thing I ‘ve said so far has to do with unit testing, not JUnit specifically.
