Unit2: Code Review & Testing
this unit will cover:
- Differentiate between various testing strategies
- Write professional guidelines
- Sound more natural and smooth when asking questions
- Use colloquial language in speaking to give and accept feedback
vocabulary - None Pharses 词汇: 名词短语
Testing 测试是软件开发中的重要短语, 用于检查软件是否达到特定的标准和用户需求.
使用这些名词语句来证明英语名词的专业性:
| None | Desciption | Example |
|---|---|---|
| time box | an allocated period of time for completing a task | - allcate a 2-hour time box for regression testing |
| stress test | a method to assess a system’s performance under heavy loads | - simulate 1000 users accessing the login page at the same time |
| sanity check 健全性测试 | a quick check to verify that something is as expected | - are the units of the output value correct? |
| ad hoc test 临时测试 | a test performed without predefined test cases or plans | - input unexpected characters into a search bar |
| edge case | a problem that only happens in extreme situations | - upload an empty, 0-byte file |
一些名词短语也可以当作动词使用:
- Can you sanity check my email before I send it? I want to make sure there aren’t any errors.
- We have a lot to do today. Let’s time box this meeting so we stay on sechedule.
BE CAREFUL: sanity check vs ad hoc test
sanity check: similar to performing a review
ad hoc test: exploring issues using the tester’s knowledge
- Yesterday, while doing ad hoc test, I came across some unexpected behaviour when I was randomly interacting with the system.
- Hey, I made a few changes to the codebase. Can you do a quick sanity check before I start testing?
Parallel Structure 平行结构
Parallel structure: Using the same grammatical structure for two or more clauses in a sentence.
Example:
“In our coding guidelines, we emphasise writing clear comments, to follow naming conventions, and maintain consistent indentation.”
注意到上面的动词了吗? (mixed verb forms)
writing = gerund form 动名词形式
to follow = infinitive form 不定式形式
maintain = base form
为了达到平行结构, 将动词修改为相同形式. 由于上面例子由 ’emphasise’ 开始, 将其改成 -ing 形式:
In our coding guidelines, we emphasise writing clear comments, following naming conventions, and maintaining consistent indentation.
平行结构的好处:
- more professional
- more effective
- easier to read and follow
You can apply this technique when writing:
- documentation
- code comments
- best practices guidelines
Connected Speech 连贯的语言
When we talk in everyday conversations, our words shouln’t stand alone.
Instead, some sound, words and phrases are merged together in what’s called connected speech. It’s a natural rhythm and flow taht make conversations sound more smooth.
Let’s take a closer look at three different techniques that your can use while asking questions:
同化 Assimilation
将两个音素融合形成新音素.
如"could you"中/d/与/j/融合发成/dʒ/, 形成"coujoo"的流畅发音. /d/ + /y/ = /dʒ/省略 Reduction
缩短或省略特定音素.
如"who is"中/oʊ/和/ɪ/压缩为长元音/uː/, 读作"hooz"连读 Linking
将前词尾音与后词首音无缝连接，无停顿.
如"how about"中/w/与/ə/自然衔接, 形成连贯语流.
Code Review
Tom: Hey Sophie!
Sophie: Hi! How are you?
Tom: All good, all good. So I’ve reviewed the changes that you made to the ETL pipeline. Overall, it looks great, but I’ve got a few points I’d like to go over.
Sophie: Sure ok, let me pull it up. Ok I’m ready, go ahead.
Tom: Fristly, in the data transformation phase, I noticed a nested loop structure that might impact performance when we go handle large datasets. Have you thought about optimising this bit?
Sophie: Yeah, I see what you mean. So, instead of a loop, what are you thinking?
Tom: I was thinking you could use a list comperhension for that part.
Sophie: Ok sure, let me go back and review it and I’ll give that a go.
Tom: In terms of error handing, I noticed some areas where execptions aren’t being caught properly. These are crucial since it means it’s not going to crash the entire system.
Sophie: Ok good point. I’ll have a go at adding some try-except blocks here and then I’ll go over the error logging to make sure we’ve got details if there are any exceptions.
Tom: Sound good. On a positive note, I really like how you refactored the data loading module. It’s much cleaner and easier to follow now.
Sophie: Oh yeah it was a bit of a mess to be honest so it did need a good tidy up. Any other points?
Tom: Nope I think that’s everything, overall, it’s looking really solid. I’ll leave some comments on the code with everything that I’ve mentioned for improvement, but great work overall. Well done.
Sophie: Perfect. Thank you. Thanks for the feedback. I’ll get started on those and then I’ll let you know when it’s good to go.
Tom: Alright. Thanks! Have a great day. Bye.
Sophie: Yep and you! Bye.
词汇解释
- go over: discuss
- pull it up: open the code on my scream
- have/give a go: try
- how you reafactored: the changes you made
- tidy up: reorganizing
- looking really solid: very well structured
