Other Extensions Introduction The Common Lisp standard allows considerable latitude in the details of an implementation, and each particular Common Lisp system has some idiosyncrasies. This chapter describes ordinary user-level features of Clozure CL, including features that may be part of the Common Lisp standard, but which may have quirks or details in the Clozure CL implementation that are not described by the standard.
In contrast, we are not satisfied with the central content. Here are my notes: Information objectives drive the testing mission and strategy When you test a product, you have a defining objective.
What are you trying to learn about the product? Your mission is to achieve your information objective. So the information objective is more about what you want to know and the mission is more about what you will do. This is where we introduce context-driven testing. The missions differ here, and so do the strategies for achieving them.
The distinction between information objective and mission is too fine-grained. It led to unhelpful discussions and questions.
We gave students an assignment, in which we described several contexts and they had to discuss how testing would differ in them. This was too hard for too many students.
We have to provide a better foundation in the lecture and reading. Back when we created BBST 3. The world has moved on, and what was, to some degree, hypothetical or experimental, has become established.
Several different contexts grew out of the Agile Manifesto. Whether we think this approach is wonderful or not, we should recognize it as a common context.
A context-respecting tester who works for, or consults to, a company that develops software this way is going to have to figure out how to provide valuable testing services that fit within this model. Context-driven testing requires the tester to adapt to the context—or leave.
The career issues were often visible in the classes, but there was no place in the course to work on them. Continue with this as the course opener. Merge information objectives and mission into one concept mission which drives strategy.
Tighten up on the set of definitions. Create a separate, well-focused treatment of career paths in software testing. This will become a supplementary video, probably presented in the lesson that addresses test automation. Oracles are heuristic An oracle is a mechanism for determining whether a program passed or failed a test.
InElaine Weyuker pointed out that perfect oracles rarely exist and that in practice, we rely on partial oracles. A heuristic is a fallible but reasonable and useful decision rule. The heuristic aspect of a heuristic oracle is the idea that the behavior of software should usually but not always be consistent with a reasonable expectation.
Bach developed a list of reasonable expectations, such as the expectation that the current version of the software will behave similarly to a previous version.
This is usually correct, but sometimes it is wrong because of design improvement. Thus it is a heuristic. After the explanation, students worked through a challenging group assignment.
We gave students some required readings, plus quiz questions and exam study guide questions but no assignment. This material worked well for RST. It did not work well in BBST. I published a critique:Fluentd uses MessagePack for all internal data representation. It's crazy fast because of zero-copy optimization of msgpack-ruby.
Now MessagePack is an essential component of Fluentd to achieve high performance and flexibility at the same time. "Section 2—Filing Requirements" helps you decide if you even have to file. "Section 3—Line Instructions for Form EZ" follows the main sections of the form, starting with "Top of the Form" and ending with "Signing Your Return.".
About These Instructions. We have designed the instructions to make it as simple and clear as possible to file your tax return. We did this by arranging the instructions for Form EZ preparation in .
I'm working on application that downloading mp3 files to mp3 player. The SanDisk doesn't have a drive letter and uses MTP for file transfer. i tryed with a sample of connecting to the device at.
Clozure CL is a fast, mature, open source Common Lisp implementation that runs on Linux, Mac OS X, FreeBSD, and Windows. Clozure CL was forked from Macintosh Common Lisp (MCL) in and the development has been entirely separate since.
