Investigators: Chainsaw likely sparked Birch Bay Fire



Trees burnt down

A wildfire in northern Minnesota near Ely that has burned an estimated 33 acres likely originated from chainsaw work done by U.S. Forest Service crews.

The Birch Bay Fire started on June 1 eight miles northwest of Ely and was 100 percent contained as of Saturday.

A Minnesota Department of Natural Resources fire investigator determined the fire was likely caused by “chainsaw operations” during prescribed burn preparation work, which are designed to burn off brush and other fuel to help prevent bigger wildfires, according to a U.S. Agriculture Department news release.

Chainsaws can easily ignite dry grass, needles or woody debris via contact with their hot engines, scorching exhaust or sparks.

“We are committed to transparency regarding the findings of this investigation and to reviewing the incident to identify lessons learned that can help inform future operations,” said Superior National Forest acting forest supervisor Drew Stroberg.

Superior National Forest spokesperson Tim Engrav said there’s a boundary established around a prescribed fire unit and crews typically must do preparation work with chainsaws before a prescribed burn.

“Typical preparation work would be to cut those trees, make sure that those lines are clear not only for holding the fire, but also for safety for firefighters to allow them to be able to get in and out during the prescribed fire operations,” he said.

The crews were working within the Geraldine Prescribed Fire project area as part of a larger Superior National Forest effort to reduce hazardous wildfire fuels and improve forest resilience.

No other prescribed burns were underway at the time the Birch Bay Fire began. Engrav said in the coming weeks, crews are expected to clean up the area, remove water hoses and pumps and see what can be rehabilitated.

“There is work that's done to kind of rehabilitate those areas if any dirt was dug up, to kind of pull that all back over,” he said. “If there's any slopes involved, to get what we call water bars in there, so when rain comes it doesn't wash all the soil away.”

Superior National Forest officials have temporarily banned campfires, including stoves and grills fueled by wood or charcoal, in the Boundary Waters Canoe Area Wilderness until June 30 as a precautionary measure to prevent more fires erupting during the current dry conditions. Gas and propane cook stoves are still permitted.

The Forest Service on Saturday afternoon reported two new wildfires within the Boundary Waters Canoe Area Wilderness.

One of them is a one-acre fire about 20 miles east of Crane Lake between Tiger Bay and Boulder Bay. The other is a five-acre fire east of East Loon Bay on Loon Lake.

Both were near two to four campsites. Engrav said firefighters were able to reduce both and will continue to work on them through Sunday and the rest of the week.

“They'll be out there as long as needed to work on containment for each of those fires,” he said.

Engrav added the public is advised to steer clear of the fire areas and cannot fly drones over wildfires or in the Boundary Waters Canoe Area Wilderness. There are no area closures, but some of the campsites nearby may be temporarily closed.

Selenium vs Tosca – Table of Content

What do you know about Selenium?

Selenium is a popular testing automation tool mainly used for web-based applications such as Selenium IDE, Selenium RC, Selenium Grid, and Selenium Web Driver. These selenium tools offer a rich set of testing features and advanced functionalities to work with various testing scenarios of all kinds of web-based applications.

Why Selenium?

The main purpose of using this testing tool is to offer high-level flexibility and also provides many options for comparing User interface elements on the base of expected application behavior. We can perform the Selenium testing process on multiple browsers. The main programming languages which we can use here are Java, Perl, and Python, Ruby, and C #.                                        

What do you know about Tosca?

Tosca is an automation tool for both functional and regression testing for several software products. This Tosca tool also includes a Graphical user interface and Command-line interface, an Application programming interface, and integrated test management. This Tosca tool was first developed by TRICENTIS technology and consulting GmbH, this is an Austrian company. This Tosca supports programming languages like visual basics, Java, and C#.

Why Tosca?

Tosca is an innovative enterprise software test tool used to optimize all various stages in test cases and to provide a robust test analysis for software applications. This tool is based on the technique of the LinearQ(sm). The one aspect of this tool that gives it an edge over the others is a model-based technique where an Application Under Test(AUT) model is generated instead of a test automation script. The Tosca platform accelerates testing in order to keep pace with DevOps and Agile.

Major differences between Selenium and Tosca testing tool

  • As we know that Tosca tool is less  popular than Selenium as it recently launched in the market.Selenium is a highly popular testing tool among the various tools available in the market.
  • No scripting is required for the Tosca tool and multiple scripts are needed for the Selenium tool.
  • The ease of tool adaptation and the ease of maintenance is very high compare to selenium whereas the adaptation and maintenance are low for selenium.
  • The type of automation is model-based in Tosca and the type of automation is code-based for the Selenium tool.
  • The reusability of test data and artifacts are high in Tosca when compare to selenium.The reusability of testing data and artifacts are low in Selenium.
  • Tosca tool has dedicated support for only deployment and adoption process Whereas Selenium lacks dedication and adoption support.
  • Tosca tool possesses huge testing capabilities for autonomous SAP tools such as SAP testing, SAP impact analysis, Business intelligence, Data warehouse test-case designs.
  • Selenium supports the autonomous testing capabilities for SAP testing, SAP impact analysis, Business intelligence, Data warehouse, test case management, test data management, and exploratory management. 
  • Tosca is a paid automation tool.Selenium is a free tool no need to pay anything.Tosca automation tool is a licensed tool and Selenium is an open-source automation testing tool.
  • The amount of coding involved in Tosca is 0.Selenium heavily depends on the coding.
  • You will get dedicated support from the Tricentis team.This doesn’t have any support. But only you can see the R and D option.
  • Tosco tool has inbuilt reporting. With this, you can see a dashboard to view the information like timing, graph, and pie chart.Selenium does not have any inbuilt reporting.
  • The Tosco framework is more or less specified and supported by the technical support team.Selenium doesn’t have any specific or particular framework.
  • The object libraries are available to manage a large number of scripts.Selenium doesn’t have any type of inbuilt object repository. So the number of scripts become too large and they are difficult to manage.The model-based test automation is the most valuable feature, where users can create reusable components. Even though we are using a script less automation tool, there still needs to be an understanding of how to create reusable components and how to keep refactoring, and how to keep regression, the test scripts, at an okay level. We are coupling Tosca with some other risk-based testing tools as well, but automation is primarily what we are using Tosca for, the script less, model-based technology that is driving automation for us.The solution is very flexible; there are different ways of using it. This is open source and offers a lot of support to users.        
  • No need of using any type of codes in Tosca, where you can use script or test cases to test the product.Selenium offers ease to write your set codes.
  • You can’t expect massive support from the community, because it is a new product. A lot of community support is available. 
  • Non developer or non-programming can use Tosca tool as it doesn’t require any code.To work on Selenium you should have a programming knowledge
