I originally posted on the uTest Forum.
In Part 1 of this series, we talked about the reasons why a uTester should focus on reporting high-value bugs. That led to some fantastic discussion and a spin-off thread about reporting every bug you find. Before you continue, you should go back and review those threads to get caught up on the topic.
In this Part 2, we are going to look at “HOW” you can find and report high-value bugs. This is a popular topic at uTest and there are many threads, webinars, and crash courses available (There are links to some of that material below). This post is intended to complement those resources and help us continue to improve our testing skills.
I’ve teamed up with fellow TTL and uMentor, Allyson Burk for a double dose of testing goodness We have some great ideas for you, so let’s get started!
Finding high-value Bugs
Focus on One cycle at a time (Allyson Burk)
I find there are two approaches to the workload at uTest: 1) accept every cycle, file a few bugs on each or 2) accept fewer cycles, file more bugs per cycle. Personally, I find the latter to be the best way to make more money, have more satisfaction in my work and increase my tester rating. Why? Because I can increase the quality of my work using this approach.
Giving myself more time on a product allows me to be methodical. I might use a few different approaches depending on the type of product.
– Deep, power user scenarios. I develop a goal in mind. A recent cycle I was on had a great example of this – you are a soccer mom and you need to equip your child for the upcoming season. This is going to yield the issues that are going to affect the target audience of the client. This approach can definitely yield high value bugs because you will be able to tell the client what is going to drive those target customers away.
– Break down the app into areas and dig deep. This is the approach I use when it is a newer, more unfamiliar application. I might spend a few hours in settings making sure each setting combination is functioning properly; or trying a variety of shopping cart, wishlist, checkout scenarios; or product customization. The key is not just spot checking to see if the area is functioning, but to really stretch the code and make sure all variables have been covered.
– Going down the rabbit hole. This is a less precise, more intuitive path where I just start investigating the parts of the application that I find interesting and following them as far as I can take them. If I really love the app or find it to be fun to use, this is the approach I will take. You have to be careful with this approach because you can “waste” a lot of time.
The key to all of these approaches is TIME. You cannot test in this deep manner if you do not have time and you cannot have time if you have 5-15 active cycles clamoring for your attention.
(Note from Lucas)
When you accept a new cycle, you are expected to thoroughly read the scope and instructions, read through the known bug list, review any other attached documents, and catch up on any chat posts. Then you have to set up your testing environment. You have to install the app, create an account, configure your proxy, etc. These start-up activities can be quite time consuming. Keeping your active cycles low allows you to spend less time getting ready to test, and more time testing.
Know the status of a project (Allyson Burk)
In general, clients are going to value bugs differently depending on the point in the development cycle they are on. It is important to pay attention to clues about where the client is in development when searching for high value bugs. This can be a moving target depending on the methodology used, agile vs. waterfall for example, but I think for this conversation we can think in terms of early, middle and late in the development cycle.
– Early in the development cycle, you can imagine that content related bugs are not going to carry huge value. The look and feel may still be in development, the final copy is likely not completed and images may not have been delivered. The client is rather going to be more focused on core functionality. They need to make sure the major functionality is there and working properly.
– Midway through the development cycle, functionality is still going to be the focus, but content starts to be more important. If ever there was a time to value spelling/grammar bugs, this would be it. Most copy has to get locked down for legal/translation/marketing/etc. so the client may be looking to make sure this is completely clean before shipping it off for various approvals.
– Late in the development cycle, stability and polish are key. Everything needs to be functioning at this time and the application needs to have a minimum of crashing/blocking issues. Many times in this last stretch before release of a product, the client might only be interested in High or Critical issues. The code will be fairly locked down at this point. The client will often not want to risk fixes that might break other functionality, so they are really going to be interested only in bugs that are of such severity to make the app unusable.
As uTesters, I think the trickiest aspect of this is knowing what phase of the development cycle the client is on. Logic might dictate that if you are on the first cycle for a new client that they would be early in the development cycle. I’d actually venture a guess and say that is actually almost never the case given my experience. I’d say we are usually brought in after the code is pretty stable and the content is beginning to be finished… somewhere in the mid stages.
But how can we know with more certainty?
Sometimes, this is as easy as reading the overview and paying attention to context clues. The PM might explicitly state, this is the first testable build of this product (early) or this is the release candidate (late). There may be things excluded from the scope like images (early to mid). There may be a very long known issues list (mid to late) or no known issues at all (early or late – HA this is a tricky one! They may clear all known issues for the later builds in order to make sure there has been no code regression before shipping the product out).
In the end, we will have to rely on the information provided and forge ahead. There is also never any harm, if you feel that there is no clear focus provided, to ask the question: Is there anything in particular the client is wanting us to focus on at this time? You might be refreshed at what avenues of testing that will open up for you.
Writing High-Value Bug Reports
Report bugs, not symptoms (Lucas Dargis)
The other day I was the TTL of a cycle and one of the features in scope was an account creation screen. The user was required to enter several pieces of information including their Address. Two different testers report these two bugs:
Bug 1 – Address field allows “!!!!!!!!!!!!!!!!!”
Bug 2 – Address field allows “!@#$%^&*()_+”
I see this type of thing all the time, so I know some of you saying “What’s wrong with that?”. The problem is both of these testers reported different symptoms of the same bug. If they had taken some time to do further investigation into the Address field, they would have realized that they hadn’t found a specific input that made it past the validation. They would have learned that the real issue was the Address field wasn’t being validated at all. The user could have entered anything (or nothing) and the system would have accepted it.
Whenever I encounter a bug, I spend a significant amount of time testing all around it, trying different inputs and different sequences of events until I understand the root cause and all of its symptoms. This is where testers can show their worth. It’s easy to click on something and then report on the results, but it takes a much stronger skill set to be able to investigate potential bugs and then provide a valuable report of your findings. Customers can see this effort and they usually reward it.
Sell Your Bugs’s Prominence (Lucas Dargis)
If a bug is easy to find, it is usually more valuable then if it was an edge-case bug and it was unlikely that anyone would find it. Identifying your bug and reproduction steps is just the first step. The best testers know that how their bug report is written can affect how the customer views it’s prominence (how easy it is to find). The best testers keep their bug reports focused and their steps limited to the critical path. That means you should only list the specific actions needed to trigger the bug.
There is a problem with this approach. Often, bugs are hidden deep within the application and you might feel that you need to explain how you arrived at the bug. The way I get around this concern is to list “Prerequisite” steps at the top of the “Actions Performed” where I describe the starting state of the application.
Bug Title: Shopping Cart – Items added to the cart are not saved
1. Go to the URL
2. Click on create new account
3. Enter a valid username
4. Enter and password
5. Click “Submit”
6. Log into the system with your account
7. Search for an item
8. Select the item
9. Add the item to my cart
10. View your shopping cart
The above report lists the steps from beginning to end, but it is fairly long and gives the impression that a user would have to do a series of very specific steps in order to find the bug. Instead, you should only list the steps that are directly related to the bug. Let’s see what that would look like.
Bug Title: Shopping Cart – Items added to the cart are not saved
Starting state – User is logged into the application and viewing the details page for a product
1. Add the item to my cart
2. View the shopping cart
Explaining the starting state at the top of the report allows us to remove 8 steps. Now, because only the steps that specifically cause the bug are listed, this bug seems much more prominent and the report does a better job of highlighting the value of the bug. This is an oversimplified example but I hope you understand the point.
This is just one tip on how to sell your bug. This technique is called “Bug Advocacy” and is something ever tester should learn. To learn more about Bug Advocacy, here is a fantastic paper written by Cem Kaner:http://www.kaner.com/pdfs/bugadvoc.pdf
I want to thank Allyson for her contributions to this article. Please feel free to post questions, comments or challenges to anything we’ve written. Hopefully these ideas will prove useful to you in your quest for those high-value bugs.
