Missing package imports in test cases

[Prajna1999]

Inside the test/* folder almost all scripts are missing top level package import. For instance, inside
test/dataobjects.jl following imports are missing and the interpreter throwing Variable not defined inside "Main" error.

test/dataobjects.jl
# constants
DATA_SIZE = 400;
COLUMN_NO = 100;

# global variables
random(x) = rand(MersenneTwister(123), x);
data_vector = randn(DATA_SIZE);
integer_data_vector = rand(-100:100, DATA_SIZE);
data_array = Array([data_vector data_vector]);
data_array_long = reduce(hcat, [randn(DATA_SIZE) for i in 1:COLUMN_NO])

column_vector = ["data$i" for i in 1:COLUMN_NO]

index_range = 1:DATA_SIZE;
index_integer = collect(index_range);
index_timetype = Date(2007, 1, 1) + Day.(0:(DATA_SIZE-1));

df_vector = DataFrame([data_vector], ["data"]);
df_integer_index = DataFrame(Index=index_integer, data=data_vector);
df_timetype_index = DataFrame(Index=index_timetype, data=data_vector);
df_timetype_index_long_columns = insertcols!(
    DataFrame(data_array_long, column_vector), 1, :Index => index_timetype)

should instead be

using Random
using DataFrames
using Dates

....other lines remain the same

@chiraganand can you label it as a bug?

The testing framework automatically imports the packages defined in a dependencies file.
