Well, in such case you need to convince the customer that Api Testing is extra work and will consume significant resources. Tell him if Api Testing is included in-scope the budget will increase by XYZ amount. Important aspects like test estimation, test scope, Test Strategy are documented in Test Plan, so it can be reviewed by Management Team and re-used for other projects. Test Plan writing requires strong analytical skills, attention to detail, and the ability to think several moves ahead.

An Eulerian-Eulerian approach, standard k-ε turbulence model, and multiple reference frames technique were employed to simulate the solid-liquid two-phase flow, turbulent flow, and impeller rotation, respectively. The effects of impeller speed, impeller type, impeller spacing, impeller blade tilt angle, impeller blade shape, solid particle size and initial solid particle loading on the solid particle suspension quality were investigated. Results showed that the homogenous degree of solid-liquid system increased with the increase of impeller speed. The impeller spacing of T5/6 and T and impeller blade tilt angle of 60° and 45° were appropriate for the solid-liquid suspension process. Fractal shape impeller was more efficient than jagged shape impeller in solid-liquid mixing process. Larger particle diameter and higher initial solid particle loading resulted in less homogenous distribution of solid particles.

Hardware or software resources are available as per the requirements. The Board on Academic Honesty can impose suspension for one or more semesters. Students suspended for academic dishonesty are withdrawn from the University after any appeal has been processed. Evaluation Criteria means the criteria set out under the clause 27 of this Part C, which includes the Qualifying Criteria, Functional Criteria and Price and Preferential Points Assessment. The student’s total number of non-passing grades for the most recent term is anything greater than what is listed under the Academic Suspension criteria.

In closing, it’s worth stating that the creation of a test plan does not need to follow a particular format. What matters most is the intent and information provided in the document. Whichever style you choose, it is recommended that you keep the test plan concise, containing details that are specific and applicable to the project. Environmental needs vary, depending on the type of system under test.

Step 2. Create Test Logistics

First, when only a small fraction is suspended, the mixing time of the suspension is similar to the case of liquid only. At this point, the liquid circulates efficiently and the few suspended particles may be distributed almost throughout the vessel. With increasing agitation, a larger fraction of the particles are suspended resulting in a non-steady circulating flow and decreased cloud height. The longest mixing time is measured at this point and a further increase in the agitation rate increases the cloud height while the mixing time decreases.

Test artifacts are by-products generated during the software testing process and shared with the project team. Simply put, these are documents that bridge the communication gap between all the members. EIT based systems are evaluated to measure various types of multiphase flow such as petroleum industry, oil and water flows , cement rock and water . In suspension criteria in testing Tervasmäki et al. ; Wang et al. and Liu et al. distribution of the solid phase in multiphase flow in pipe have been presented. Silva et al. investigated characterizations of solid–liquid settling suspensions such as flow regime and deposition velocities based on size of particles in a pipe with 10 cm diameter and salinity of 696 μS cm−1 using EIT.

Risks and Contingencies

As you can see, a Test Plan is voluminous, often difficult to write, but a crucial testing artifact. It guides the team through a well-structured testing process, preventing a lot of stressful situations and misunderstandings. Moreover, a Test Plan helps team members stay on the same page since stakeholders and developers can have access to it.

Contour plots of CFD-predicted fluid flow patterns and fluid flow velocities for three different working volumes. The fluid flow patterns and the fluid flow velocities are shown for 25 rpm and 10°. Comparison of volume-weighted mean fluid flow velocities over one period. Testing after a truly fatal error will generate conditions that may be identified as defects but are in fact ghost errors caused by the earlier defects that were ignored.

You can increase the number of team members to meet your deadlines depending on your needs. As for the equipment and system resources, you and your QA team should agree on such things as devices, networks, servers, etc. to be used during quality assurance checks. In this step, you should enumerate all the resources needed for performing tests including time, people, money, and equipment. API testing helps you check the performance, functionality, and security of application programming interfaces.

Quality control team plays a vital role in overall improvement of the software development process. Software needs include the operating system specifications such as Windows, Mac, Linux or Android. If you are testing a web application, you need to list down the browsers in your test plan on which you will perform the testing. Software test plan document contains details of the specifications needed to set up test environment.

Experimental investigation on solid dispersion, power consumption and scale-up in moderate to dense solid–liquid suspensions

In Utah, cloud seeding programs are suspended upon the evaluation of percentage of mean SWE values. The current monthly SWE threshold values considered for January 1, February 1, March 1, and April 1 are 200%, 180%, 160% and 150% of average values, respectively. However, the suspensions for severe weather are done regardless of current SWE values. Solid–liquid suspensions are encountered frequently in different areas of process industries, and stirred vessels used in mixing the two phases have been under extensive research for decades.

  • There can be some features or functionalities which are neither clearly out of scope nor could be tested due to any reason.
  • We assist companies to increase the quality of product deliverables by improving ability to release products quicker and more often.
  • Fractal impeller could decrease the Njs and Njd on the basis of four pitched-blade impeller, and decreasingly so with the fractal iteration number.
  • Simply put, these are documents that bridge the communication gap between all the members.
  • It guides the team through a well-structured testing process, preventing a lot of stressful situations and misunderstandings.
  • The results indicates that southern China has more precipitation but it varies widely in different periods during the year.

Maritime air mass from the Bay of Bengal favours a clean atmosphere that supports clouds with fewer droplets, and the effective radius crosses above 12 μm below the 10 °C temperature level. Thus CA is mainly characterised by moderate precipitation efficiency and broader hydrometeors size distribution spectra. As the concentration of sea salt, dust particles, moisture content, and convective available potential energy increases, MPA profoundly supports the primary and secondary ice nucleation inside the convective system.

In a way, it unites project team members around the same goal, providing a clear understanding of the hierarchy, tasks, and expected outcomes. Staffing and training needs – List the required resources and all types of training needed for a smooth execution of the project, including the identified skills and resources needed for the training. The reason for including this information is to help with developing the training plan, and provide a better idea of the total time required and cost involved in training.
