Embedded testing - Embedded software (Part 3)

 In continuation of the previous post, "Embedded system," let's examine embedded software and how it plays a major role in physical devices.

An application software is a computer program that provides functionality on a computer. It is specifically made for consumers to use. However, embedded software is computer software that is written for controlling physical machines to operate. Most of the embedded software is written in C, C++, and C#. In recent times, Javascript, Java, and Python also come into the picture to control embedded systems.

Embedded software is like a well-organized but strict boss living inside the machine or device. It is tiny, invisible, and works behind the scenes to make sure the machine does not crash.

How does the embedded software work?

Embedded software is a manager who sits in the office and manages the team (hardware)

Providing instructions: This manager never calms down and he/she keeps on giving instructions to the team. 

  • To check the temperature and collect the data every second.
  • Ask the motor to keep running until the manager says STOP.
  • Smart light sensor, turn ON when I clap and OFF when I clap two times or after one hour. Got it?
Monitoring: The manager's job is not only giving instructions but also checking if everyone is doing their job right.
  • Is the temperature under control?
  • Is the motor running smoothly?
Handling emergencies: When things go wrong, the manager keeps cool and makes quick decisions.
  • Is the battery about to die to spin the motor? Switch to backup power!
  • Is the motor overheating due to the continuous progress? Stop the motor when it blows up!
Multitasking: Embedded software is a super-efficient manager that handles many tasks at a time.
  • Checking the temperature is fine when the motor spins.
  • It will handle when the light blinks too often.
  • Make sure the machine has backup power when it needs.
On the whole, embedded software is a manager who never takes a rest, never goes for a coffee break, never loses temper, and always keeps the team working like a well-oiled machine.

How to Install Jenkins

Image
Jenkins is an open-source Java application server for Continuous Integration and Continuous Delivery (CI/CD). This will run in servlet containers such as Apache Tomcat. It helps the developers to build, test, and deploy the software by automating using CI/CD pipelines. It detects bugs and notifies the developers in an early stage. How to Download and Install: Step 1: Go to https://www.jenkins.io/ . Click Download Step 2: Download Jenkins ‘Generic Java package’. I prefer to download the LTS package (It is a stable one). Step 3: Select your desired path after downloading and save the Jenkins.war file in your local system. Step 4: Go to command prompt (Windows) | Terminal (IOS)                Go to the folder where the war file is saved. Then, type the command java -jar Jenkins.war and run it. It will take a while to run the command. It gives an admin password. Note it down to use Jenkins the first time. The ...

HTTP Payloads

Image
 What happens when I send a letter without information to the receiver that I require some details from them? What happens when the receiver writes a response to my letter without having the information I need? This information is similar to the body generally called a payload in HTTP request and response.  Let us see the payload in the HTTP request and HTTP response individually. I have added the below image to explain the HTTP request and response body/payload in JSON. I have used BurpSuite to take this image and Swagger Petstore (petstore.swagger.io) for this example. HTTP Request Payload Generally, the payload is not required for all the requests and responses. GET and HEAD methods usually do not require a body while sending a request to the server. The above example is a POST request to create a resource name 'doggie'. To achieve this, I should send some information about the resource which is called HTTP request payload. Breakdown of request payload: Content-Type:  ...

Embedded testing - Introduction (Part 1)

 I'm writing a series about my recent learnings in embedded testing. Here is the basic introduction about this topic with a simple example. Scenario 1: A patient books an online appointment to provide a blood sample for a hemoglobin level test. To book an appointment, the patient only needs access to a web or mobile application. When a quality engineer tests the functionality of this appointment registration process, it is referred to as software testing. Scenario 2: The patient now wants to collect the test report after the blood sample analysis. To measure the hemoglobin level, the lab technician uses an automated medical device. At this stage, if the quality engineer is involved in testing, they require both a physical device (hardware) to process the sample and an application (software) to enter or capture the details. When testing involves both hardware and software, it is referred to as embedded testing. Click here to read the next blog
