Basic instructions of manual testing



Hello everyone! I'm Linh here.

In the work related to testing software, we often have a lot of different forms of testing such as: E2E Test, Test coverage, Logic Test, Manual Test, etc. However, for a beginner like us, we usually start with Manual Tester to test a first website. Then, I am going to share to you some Tester experience which I was trained by my sister. She is Hoa who has 10-year experience in tester, taught me about Manual Testing.

First of all, we have to understand what is Manual Testing?

Manual Testing is a method of testing software or a programme that is performed manually by testers without going through any testing automation tools.

It is used based on the purpose of detecting from small to big bug errors in the programme.

From that, it gives solutions to make sure that the software is in the most stable operation when delivering to customers.


We know that each work also has strengths and weaknesses and Manual testing don't except.


  • Manual testing helps us save fee.
  • It receives feedback quickly and intuitive about designed software interface.
  • When it has small changes, it helps us to save time for testing software.
  • There are many oppoturnities for testing to find out complex mistakes, which also helps tester to increase skill.


  • Tester spends a lot of time and efforts looking for errors.
  • Fail-safety, convenience of Test manual are less than these of Automation test.
  • Just be helpful while testing cases run one or two time, not unsually repeat.
  • The process of Manual Testing isn’t recorded, therefore it can’t reuse in other testing situations.

Some Manual Testing technique:

  • Checking the interface is correct with design (desktop/mobile, responsive layout is fine).
  • Testing font-size, color, font-family, font-weight, line-height correctly and compare with design by tool WhatFont
  • Link/ button is always in hover + hand icon when moving to hover. cursor-pointer.png
  • Padding left/right top/bottom always have same level (except some especial situations).
  • Add icon loading site.
  • Space between modules isn’t too wide/ too narrow (desktop/responsive/mobile).
  • No horizontal scrolling.
  • Do have favicon site. favicon-site.jpg

1. About the Logo, Menu, Breadcrumb.

a. Logo + Menu:
  • The logo must have a link to home. logo-link.png
  • The logo is not scaled.
  • There is a hand icon for the menu with the link, the destination is the correct link.
  • Has hover/active state.
  • Entering “son” menu have to activate “Dad” menu. menu.png
  • No activate 2 menus in a time.
  • Scroll to the bottom of the menu pin (optional but required for users’ convenience).

b. Breadcrumb:


  • Correct level of Home/ menu/ detail.
  • The bottom level breadcrumb has no links.
  • Up-level Breadcrumb must return to the correct link.

2. Search

  • For hidden search, when clicked -> show the search box.
  • Click on the search icon when you haven’t entered anything -> display a blinking cursor in the search box.
  • Add text in the search box enter or click search icon to have an action.
  • Search with special characters on the keyboard: !@#$%^&*(){}[]<>?/:'” -> so that see errors.
  • Page search has the format /search?keyword /search?q=test or may be different depending on the language.
  • Test page search results: search results based on title + detail, for example to search "test" will filter out all pages that contain the word test.
  • Page search with multiple results will display by paging/Load more or load when scrolling.
  • Click on the right search result to go to the right page.
  • Do not repeat search results.

3. Image

  • An image must have alt (background is not needed) alt-image.png
  • Alt image is now correct as entered, use this link to check: Web Developer Chrome Extension
  • Image is not scaled.
  • Image size should not be too big (optimize at https://tinypng.com/) standard size less than 200kb, for banner images or high quality images it is possible.
  • The image size resizes to the correct standard, for example, the width height only needs to be 400x400px, but the original image is 1500x1500, then resize to the correct or maximum double 800x800px.

4. Form

  • The form includes mandatory fields (fields marked with *) and optional fields (fields without a *). form.png

  • Submit without filling in info -> the required fields must have a red border and the text message line requires information to be entered (otherwise, the optional fields are not needed).
  • Email, phone must fill in the correct format for the new pass, email has the extension @, phone includes a number and “+”.
  • Testing submit form multiple times.
  • Fill in the form information and wait a few minutes before submitting (see if there is a timeout).
  • After submitting the form, you must clear all previous information, move to the page “thank you”. submit-form.png

5. Rule heading H

  • Read this blog to have understand clearly about heading H (https://seotongthe.vn/the-heading/ ).
  • 1 page must have 1 heading H1.
  • Determine the content of a page to set H correctly.
  • 2 identical content cannot have 2 different H tags. image.png

In conclusion, to become a Manual Testing professional in the future, we need: you must determine your desire and what you love, abilities in yourself such as: what you should invest, learn, which skills you should improve and how to get they, how to practice and use them, etc. These things will help to give decision by yourself and make you put your effort in order to achieving them.
