Not able to run basic test using webdriver IO



I am new to webdriver I am trying to run following code


var assert = require('assert');
describe('webdriver.io page', function() {
it('should have the right title', function () {
browser.url('/');
var title = browser.getTitle();
assert.equal(title,'WebDriverIO - Selenium 2.0 javascript bindings for nodejs');

});
});



When I am trying to run $npm test it is giving me following exception

Makefile test if variable is not empty

Makefile test if variable is not empty In a makefile I'm trying to I've created this simplified makefile to demonstrate my problem. Neither make a or make b executes the body of the if, I don't understand why not. make a make b .PHONY: a b a: $(eval MY_VAR = $(shell echo whatever)) @echo MY_VAR is $(MY_VAR) $(info $(MY_VAR)) ifneq ($(strip $(MY_VAR)),) @echo "should be executed" endif @echo done b: $(eval MY_VAR = $(shell echo '')) @echo MY_VAR is $(MY_VAR) $(info $(MY_VAR)) ifneq ($(strip $(MY_VAR)),) @echo "should not be executed" endif @echo done I'm using $ make --version GNU Make 3.81 There are several problems, and misunderstandings. Your MY_VAR is a make variable, set it without a <tab> to its value, and no need to $(eval ...) . MY_VAR:=$(shell echo whatever) is enough. No <tab> before $(info ...) neither, this is make – Zelnes

Clash Royale CLAN TAG #URR8PPP 'Series' object is not callable Error / Statsmodels illegal variable name Update: You can download my dataset here. I am running a simple OLS regression with statsmodels and pandas dataframe as following: import statsmodels.formula.api as sm import pandas as pd df=pd.read_csv("exp.csv") #df is a dataframe that I have containing many variable names such as AAPL, SPY, INF, etc. for column in df: result=sm.ols(formula="SPY"+" ~ "+column, data=df).fit() However, one of the column name in df is INF . I guess maybe INF is a reserved word for pasty, the code gives me the following error: INF INF Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/ap248/.local/easybuild/software/2017/Core/miniconda2/4.3.27/lib/python2.7/site-packages/statsmodels/base/model.py", line 155, in from_formula missing=missing) File "/home/ap248/.local/easybuild/softw
